The American Joint Committee on Cancer: the 7th Edition of the AJCC Cancer Staging Manual and the Future of TNM

Abstract: The American Joint Committee on Cancer and the International Union for Cancer Control update the tumor-node-metastasis (TNM) cancer staging system periodically. The most recent revision is the 7th edition, effective for cancers diagnosed on or after January 1, 2010. This editorial summarizes the background of the current revision and outlines the major issues revised. Most notable are the marked increase in the use of international datasets for more highly evidenced-based changes in staging, and the enhanced use of nonanatomic prognostic factors in defining the stage grouping. The future of cancer staging lies in the use of enhanced registry data standards to support personalization of cancer care through cancer outcome prediction models and nomograms.

Abstract: Department ofSurgery, Thoracic Service, Memorial Sloan-Kettering Cancer Center, New York, NYIn previous editions of the American Joint Committeeon Cancer (AJCC) Cancer Staging Manual, esophagealcancer staging was neither data driven nor harmonized withstomach cancer. The new staging system presented in the7th edition of the AJCC Cancer Staging Manual, in con-trast, is data driven and harmonized.

Improving Breast Cancer Surgery: A Classification and Quadrant per Quadrant Atlas for Oncoplastic Surgery

Abstract: Oncoplastic surgery (OPS) has emerged as a new approach for extending breast conserving surgery (BCS) possibilities, reducing both mastectomy and re-excision rates, while avoiding breast deformities. OPS is based upon the integration of plastic surgery techniques for immediate reshaping after wide excision for breast cancer. A simple guide for choosing the appropriate OPS procedure is not available. To develop an Atlas and guideline for oncoplastic surgery (OPS) to help in patient selection and choice of optimal surgical procedure for breast cancer patients undergoing BCS. We stratify OPS into two levels based on excision volume and the complexity of the reshaping technique. For resections less than 20% of the breast volume (level I OPS), a step-by-step approach allows easy reshaping of the breast. For larger resections (level II OPS), a mammoplasty technique is required. We identified three elements that can be used for patient selection and for determination of the appropriate OPS technique: excision volume, tumor location, and glandular density. For level II techniques, we defined a quadrant per quadrant Atlas that offers a different mammoplasty for each quadrant of the breast. OPS is the “third pathway” between standard BCS and mastectomy. The OPS classification and Atlas improves patient selection and allows a uniform approach for surgeons. It proposes a specific solution for different scenarios and helps improve breast conservation outcomes.

Local and distant immunity induced by intralesional vaccination with an oncolytic herpes virus encoding GM-CSF in patients with stage IIIc and IV melanoma.

Abstract: An oncolytic herpes simplex virus engineered to replicate selectively in tumor cells and to express granulocyte–macrophage colony-stimulating factor (GM-CSF) was tested as a direct intralesional vaccination in melanoma patients. The work reported herein was performed to better characterize the effect of vaccination on local and distant antitumor immunity. Metastatic melanoma patients with accessible lesions were enrolled in a multicenter 50-patient phase II clinical trial of an oncolytic herpesvirus encoding GM-CSF (OncovexGM-CSF). An initial priming dose of 106 pfu vaccine was given by intratumoral injection, followed by 108 pfu every 2 weeks to 24 total doses. Peripheral blood and tumor tissue were collected for analysis of effector T cells, CD4+FoxP3+ regulatory T cells (Treg), CD8+FoxP3+ suppressor T cells (Ts), and myeloid-derived suppressive cells (MDSC). Phenotypic analysis of T cells derived from tumor samples suggested distinct differences from peripheral blood T cells. There was an increase in melanoma-associated antigen recognized by T cells (MART-1)-specific T cells in tumors undergoing regression after vaccination compared with T cells derived from melanoma patients not treated with vaccine. There was also a significant decrease in Treg and Ts cells in injected lesions compared with noninjected lesions in the same and different melanoma patients. Similarly MDSC were increased in melanoma lesions but underwent a significant decrease only in vaccinated lesions. Melanoma patients present with elevated levels of Tregs, Ts, and MDSC within established tumors. Direct injection of OncovexGM-CSF induces local and systemic antigen-specific T cell responses and decreases Treg, Ts, and MDSC in patients exhibiting therapeutic responses.

Peritoneal Carcinomatosis from Gastric Cancer: A Multi-Institutional Study of 159 Patients Treated by Cytoreductive Surgery Combined with Perioperative Intraperitoneal Chemotherapy

Abstract: Background Peritoneal carcinomatosis (PC) from gastric cancer has long been regarded a terminal disease with a short median survival. New locoregional therapeutic approaches combining cytoreductive surgery with perioperative intraperitoneal chemotherapy (PIC) have evolved and suggest improved survival.

Surgical Management of Hepatic Neuroendocrine Tumor Metastasis: Results from an International Multi-Institutional Analysis

Abstract: Background Management of neuroendocrine tumor liver metastasis (NELM) remains controversial, with some advocating an aggressive surgical approach while others have adopted a more conservative strategy. We sought to define the efficacy of the surgical management of NELM in a large multicenter international cohort of patients.

Chromogranin A—Biological Function and Clinical Utility in Neuro Endocrine Tumor Disease

Abstract: Neuroendocrine tumors (NETs) are a form of cancer that differ from other neoplasia in that they synthesize, store, and secrete peptides, e.g., chromogranin A (CgA) and amines. A critical issue is late diagnosis due to failure to identify symptoms or to establish the biochemical diagnosis. We review here the utility of CgA measurement in NETs and describe its biological role and the clinical value of its measurement. Literature review and analysis of the utility of plasma/serum CgA measurements in NETs and other diseases. CgA is a member of the chromogranin family; its transcription and peptide processing are well characterized, but its precise function remains unknown. Levels are detectable in the circulation but vary substantially (~25%) depending on which assay is used. Serum and plasma measurements are concordant. CgA is elevated in ~90% of gut NETs and correlates with tumor burden and recurrence. Highest values are noted in ileal NETs and gastrointestinal NETs associated with multiple endocrine neoplasia type 1. Both functioning and nonfunctioning pancreatic NETs have elevated values. CgA is more frequently elevated in well-differentiated tumors compared to poorly differentiated NETs. Effective treatment is often associated with decrease in CgA levels. Proton pump inhibitors falsely increase CgA, but levels normalize with therapy cessation. CgA is currently the best available biomarker for the diagnosis of NETs. It is critical to establish diagnosis and has some utility in predicting disease recurrence, outcome, and efficacy of therapy. Measurement of plasma CgA is mandatory for the effective diagnosis and management of NET disease.

Clinicopathologic Features of Non-Small-Cell Lung Cancer with EML4–ALK Fusion Gene

Abstract: A fusion gene between echinoderm microtubule-associated protein-like 4 (EML4) and the anaplastic lymphoma kinase (ALK) has recently been identified in non-small-cell lung cancers (NSCLCs). We screened for EML4–ALK fusion genes and examined the clinicopathological and genetic characteristics of fusion-harboring NSCLC tumors. We examined 313 NSCLC samples from patients who underwent resection at our hospital between May 2001 and July 2005. We screened for the fusion genes using reverse-transcription polymerase chain reaction (RT-PCR) assay and confirmed the results with direct sequencing. We also examined mutations in the epidermal growth factor receptor (EGFR), KRAS, and ERBB2 genes. Five EML4–ALK fusion genes were detected (four from 111 female samples and one from 202 male samples; 1.6% overall). All five genes were found in adenocarcinomas and accounted for 2.4% of the 211 adenocarcinoma samples. One EML4–ALK fusion was variant 1, and two were variant 3. In addition, we also found two new fusion variants. Patients with fusion-positive tumors were nonsmokers or light smokers. Among the 211 adenocarcinomas, mutations in EGFR, KRAS, and ERBB2 were detected in 105, 29, and 7 tumors, respectively. Interestingly, all of the fusion-positive NSCLCs had no mutations within these genes. EML4–ALK fusion genes were observed predominantly in adenocarcinomas, in female or nonsmoking populations. Additionally, the EML4–ALK fusions were mutually exclusive with mutations in the EGFR, KRAS, and ERBB2 genes.

Safety and efficacy of microwave ablation of hepatic tumors: a prospective review of a 5-year experience.

Abstract: This study was designed to evaluate the safety, efficiency, effectiveness, and overall long-term outcome in patients treated with microwave thermal ablation of hepatic tumors. Microwave ablation technology represents the next generation in ablative techniques for the treatment of hepatic malignancies. Currently there have been no large reports of its use in the United States with appropriate long-term follow-up. An institutional review board-approved prospective phase II study of microwave ablation of hepatic malignancies from January 2004 to January 2009 was performed. All complications were recorded up to 90 days from operation and reported using an established five-point grading scale. One hundred patients underwent 270 ablations for hepatic malignancies. The most tumor types were as follows: metastatic colorectal cancer (50%), hepatocellular carcinoma (17%), metastatic carcinoid (11%), and other metastatic disease (22%). A majority of patents (53%) underwent combination hepatic resection and microwave ablation; 38% underwent ablation alone, 9% underwent ablation and additional organ resection, with 68% open procedures. Median tumor size was 3.0 (range, 0.6–6.0) cm, median number of tumors was 2 (range, 1–18), and median total ablation time was 13 (range, 5–45) min. Overall 90-day mortality was 0% and morbidity was 29%. One patient developed a hepatic abscess and no patients experienced bleeding complications. After a median follow-up of 36 months, 5 patients (5%) had incomplete ablation, 2 (2%) had local recurrence at the ablated site, and 37 (37%) developed intrahepatic recurrence at nonablated sites. Microwave ablation of hepatic tumors is a safe and effective method for treating unresectable hepatic tumors, with a low rate of local recurrence.

Aggressive Surgery in Retroperitoneal Soft Tissue Sarcoma Carried Out at High-Volume Centers is Safe and is Associated With Improved Local Control

Abstract: Background We sought to assess morbidity and mortality in primary retroperitoneal soft tissue sarcomas (RSTS) treated by a frontline aggressive surgical approach.

Extended Preoperative Chemotherapy Does Not Improve Pathologic Response and Increases Postoperative Liver Insufficiency After Hepatic Resection for Colorectal Liver Metastases

Abstract: The optimal duration, safety, and benefit of preoperative chemotherapy in patients with colorectal liver metastases (CLM) are unclear. We evaluated the association between the duration of preoperative chemotherapy with 5-fluorouracil (5-FU), leucovorin, oxaliplatin (FOLFOX) ± bevacizumab, pathologic response, and hepatotoxicity after hepatic resection for CLM. A total of 219 patients underwent hepatic resection following FOLFOX with or without bevacizumab and were divided into 2 groups according to the chemotherapy duration: 1–8 cycles (short duration [SD]; N = 157) and ≥9 cycles (long duration [LD]; N = 62). The frequency of complete or major pathologic response, sinusoidal injury, and major postoperative morbidity were compared. Treatment consisting of ≥9 cycles was not associated with an increase in complete or major pathologic response (SD vs. LD, 57% vs. 55%; P = .74). The incidence of sinusoidal injury was higher in the LD group (26% vs. 42%; P = .017). The incidence of liver insufficiency was higher in the LD group (4% vs. 11%; P = .035). Sinusoidal injury did not predict postoperative liver insufficiency; multivariate analysis revealed ≥9 cycles was the only independent predictor of postoperative liver insufficiency (P = .031; odds ratio = 3.90). Chemotherapy including bevacizumab was associated with a significantly higher frequency of complete or major response in both SD and LD groups. Extended preoperative chemotherapy increases the risk of hepatotoxicity in CLM without improving the pathologic response. The type of chemotherapy (FOLFOX with bevacizumab) has more impact on pathologic response than the duration of chemotherapy.

Surgical Treatment of Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

Abstract: Background The role of liver resection in patients with hepatocellular carcinoma (HCC) accompanying with portal vein tumor thrombus (PVTT) remains controversial. This article aimed to evaluate the significance of different location and extent of PVTT on surgical outcomes after liver resection for HCC.

Sentinel node biopsy in head and neck squamous cell cancer: 5-year follow-up of a European multicenter trial

Abstract: Sentinel node biopsy (SNB) may represent an alternative to elective neck dissection for the staging of patients with early head and neck squamous cell carcinoma (HNSCC). To date, the technique has been successfully described in a number of small single-institution studies. This report describes the long-term follow-up of a large European multicenter trial evaluating the accuracy of the technique. A total of 227 SNB procedures were carried out across 6 centers, of which 134 were performed in clinically T1/2 N0 patients. All patients underwent SNB with preoperative lymphoscintigraphy, intraoperative blue dye, and handheld gamma probe. Sentinel nodes were evaluated with hematoxylin and eosin (HE 88% vs. 96%, P = 0.138). Also, 42 patients were upstaged (34%); of these, 10 patients harbored only micrometastatic disease. At a minimum follow-up of 5 years, the overall sensitivity of SNB was 91%. The sensitivity and negative predictive values (NPV) were lower for patients with FoM tumors compared with other sites (80% vs. 97% and 88% vs. 98%, respectively, P = 0.034). Sentinel node biopsy is a reliable and reproducible means of staging the clinically N0 neck for patients with cT1/T2 HNSCC. It can be used as the sole staging tool for the majority of these patients, but cannot currently be recommended for patients with tumors in the floor of the mouth.

Multicentric study on robotic tumor-specific mesorectal excision for the treatment of rectal cancer.

Abstract: Recently, traditional laparoscopic anterior resection has been used for rectal cancer, offering good functional results compared with open resection and resulting in better early postoperative outcomes. Few studies investigating the role of robot-assisted tumor-specific rectal surgery (RTSRS) have been carried out to show its feasibility. The aim of the study was to verify on a multicentric basis the perioperative and oncologic outcome of RTSRS. One hundred forty-three consecutive patients undergoing RTSR in three centers were reviewed. Pathologic data, and postoperative and oncologic outcome measures were prospectively collected and analyzed by an independent researcher. A total of 112 restorative surgeries and 31 abdominoperineal resections were carried out. Conversion rate was 4.9%, mean blood loss was 283 ml, and mean operative time was 297 min. The number of harvested nodes (14.1 ± 6.5) and margin status compared favorably with those of open series (mean distal margin 2.9 ± 1.8 cm; negative radial margin in 142 cases). The 3-year overall survival rate was 97%, and no isolated local recurrences were found at mean follow-up of 17.4 months. RTSRS is a safe and feasible procedure that may facilitate mesorectal excision. Randomized clinical trials and longer follow-up are needed to evaluate a possible influence of RTSRS on patient survival.

Adjuvant Chemoradiation for Pancreatic Adenocarcinoma: The Johns Hopkins Hospital—Mayo Clinic Collaborative Study

Abstract: Background Survival for pancreatic ductal adenocarcinoma is low, the role of adjuvant therapy remains controversial, and recent data suggest adjuvant chemoradiation (CRT) may decrease survival compared with surgery alone. Our goal was to examine efficacy of adjuvant CRT in resected pancreatic adenocarcinoma compared with surgery alone.

Trends in contralateral prophylactic mastectomy for unilateral cancer: a report from the National Cancer Data Base, 1998-2007.

Abstract: Background Several studies have reported an increased rate of contralateral prophylactic mastectomy (CPM) in patients with unilateral breast cancer. This study reports on CPM trends from the American College of Surgeon’s National Cancer Data Base (NCDB) diagnosed over a 10-year period.

Robotic-Assisted versus Laparoscopic Surgery for Low Rectal Cancer: Case-Matched Analysis of Short-Term Outcomes

Abstract: Purpose The aim of this study is to compare short-term outcomes and surgical quality of robot-assisted (RAP) and laparoscopic (LAP) total mesorectal excision (TME) in patients with low rectal cancer.

Sentinel Node Identification Rate and Nodal Involvement in the EORTC 10981-22023 AMAROS Trial

Abstract: Background The randomized EORTC 10981-22023 AMAROS trial investigates whether breast cancer patients with a tumor-positive sentinel node biopsy (SNB) are best treated with an axillary lymph node dissection (ALND) or axillary radiotherapy (ART). The aim of the current substudy was to evaluate the identification rate and the nodal involvement.

Prognostic Value of Metabolic Tumor Volume Measured by 18F-Fluorodeoxyglucose Positron Emission Tomography in Patients with Esophageal Carcinoma

Abstract: The aim of this study was to evaluate the prognostic value of metabolic tumor volume (MTV) measured by 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) in patients with esophageal carcinoma. We retrospectively reviewed 151 patients with pathologically proven esophageal carcinoma (146 squamous cell carcinomas and 5 adenocarcinomas) who underwent pretreatment 18F-FDG PET. MTV and maximum standardized uptake value (SUVmax) for the primary tumors were measured by 18F-FDG PET. The prognostic significance of MTV, SUVmax, and other clinicopathological variables was assessed by Cox proportional hazards regression analysis. To further evaluate and compare the predictive performance of PET parameters, MTV and SUVmax, time-dependent receiver operating characteristic curve (ROC) analysis was used. In the univariate analysis, age, American Joint Committee on Cancer (AJCC) stage, tumor–node–metastasis (TNM) factors, MTV, and SUVmax of primary tumor were significant predictors of survival. On multivariate analysis adjusted for age, sex, and treatment modality, independent predictive factors associated with decreased overall survival were T stage [hazard ratio (HR) 4.325, P = 0.006], M stage (HR 2.009, P = 0.007), and MTV (HR 1.013, P = 0.021). SUVmax was not a significant factor (HR 0.97, P = 0.061). On time-dependent ROC analysis, MTV showed good predictive performance for overall survival consistently better than SUVmax. MTV, a volumetric parameter of 18F-FDG PET, is an important independent prognostic factor for survival and a better predictor of survival than SUVmax for the primary tumor in patients with esophageal carcinoma.

Abstract: Background To evaluate risk factors for complications of tissue expander/implant and autologous tissue breast reconstructions and determine if radiation increases complication rates.

The National Cancer Data Base: Past, Present, and Future

Abstract: The National Cancer Data Base (NCDB) contains information on over 25 million cancer patients diagnosed and treated in cancer centers across the USA since 1985. The NCDB collects data on patient demographics, tumor stage and histopathology, treatment, and outcomes on more than 70% of the cancer cases diagnosed in the USA annually. Reporting centers range from small community hospitals to large academic medical centers and National Cancer Institute (NCI)-designated Comprehensive Cancer Centers. Since its inception in 1988 the NCDB has been cofunded by the American College of Surgeons (ACoS) and the American Cancer Society (ACS). The programmatic focus of the NCDB, since its founding, has been to support quality improvement at the local level.

Pathologic Response after Neoadjuvant Therapy is the Major Determinant of Survival in Patients with Esophageal Cancer

Abstract: Background Esophageal cancer remains a malignancy with high morbidity and mortality despite improvements to diagnosis, staging, chemotherapy, radiation, and surgery. Neoadjuvant therapy (NT) may improve oncologic outcome in many patients, however the degree to which patients benefit remains unclear. We examined the relationship between pathologic response to NT and magnitude of benefit in patients with esophageal cancer.

What is an adequate margin for breast-conserving surgery? Surgeon attitudes and correlates.

Abstract: Re-excision is common in breast-conserving surgery (BCS), partly due to lack of consensus on margin definitions. A population-based surgeon sample was used to determine current attitudes toward margin width and identify characteristics associated with margin choice. Breast cancer patients treated from 2005 to 2007 were identified from Los Angeles and Detroit Surveillance, Epidemiology, and End Results (SEER) registries. Pathology reports were used to identify their surgeons, who were surveyed (n = 418). Response rate was 74.6% (n = 312). Mean surgeon age was 51.9 years, 17.8% were female, and mean number of years in practice was 18.5. Wide variation in margin selection was noted among surgeons, and did not differ for invasive cancer and ductal carcinoma in situ (DCIS). In a scenario of T1 invasive cancer, 11% of surgeons endorsed margins of tumor not touching ink (TNTI), 42% of 1–2 mm, 28% of ≥5 mm, and 19% >1 cm as precluding need for re-excision before radiotherapy. On multivariate analysis, having 50% or more of practice devoted to breast cancer independently predicted smaller margin choice (p = 0.03). For a patient with a 1.4-cm grade 2 estrogen receptor (ER)-positive DCIS without radiotherapy (RT) planned, 3% of surgeons chose TNTI, 12% 1–2 mm, 25% ≥5 mm, and 61% >1 cm as sufficient without re-excision. In the scenario of DCIS without RT, breast specialization independently predicted larger margin choice (p = 0.03). Gender and years in practice were not predictive of margin choice. Wide variation in BCS margin definition exists. Variation is similar for invasive cancer and DCIS with RT, with more specialized surgeons choosing smaller margins. In DCIS without RT, more specialized surgeons favored larger margins. A standardized margin definition may significantly affect re-excision rates.

The Impact on Morbidity and Length of Stay of Early Versus Delayed Complete Lymphadenectomy in Melanoma: Results of the Multicenter Selective Lymphadenectomy Trial (I)

Abstract: Background Complete lymph node dissection, the current standard treatment for nodal metastasis in melanoma, carries the risk of significant morbidity. Clinically apparent nodal tumor is likely to impact both preoperative lymphatic function and extent of soft tissue dissection required to clear the basin. We hypothesized that early dissection would be associated with less morbidity than delayed dissection at the time of clinical recurrence.

Prophylactic Central Neck Dissection and Local Recurrence in Papillary Thyroid Cancer: A Meta-analysis

Abstract: The effectiveness of prophylactic central neck dissection (pCND) in the treatment of patients with papillary thyroid carcinoma (PTC) to prevent local recurrence is controversial. We performed a meta-analysis to assess the effect of pCND on local recurrence in PTC. Exhaustive search of online search engines identified five retrospective studies that compared the local recurrence rates of PTC in patients without clinically detectable nodal disease in patients undergoing thyroidectomy + pCND (group A) to those undergoing thyroidectomy alone (group B). A meta-analysis was performed by the fixed effects method. Recurrence was documented by imaging, thyroglobulin detection, or reoperation. Location of recurrence was identified in either the central or lateral neck compartment. A total of 1264 patients were included, 396 in group A and 868 in group B. Follow-up ranged from 6 months to 27 years. The overall recurrence rate was 2.02% in group A versus 3.92% in group B (odds ratio [OR] = 1.05, 95% confidence interval [95% CI] 0.48–2.31). The recurrence rate in the central neck compartment in group A was 1.86% compared to 1.68% in group B (OR = 1.31, 95% CI 0.44–3.91). The recurrence rate in the lateral neck compartment in group A was 3.73% compared to 3.79% in group B (OR = 1.21, 95% CI 0.52–2.75). There was no statistically significant difference in the OR in the local recurrence between the two groups. This meta-analysis indicates that pCND does not greatly reduce local recurrence in thyroid cancer. However, the available studies have substantial limitations and a prospective multicenter study to determine the indications for pCND is warranted.

Trends in and outcomes from sentinel lymph node biopsy (SLNB) alone vs. SLNB with axillary lymph node dissection for node-positive breast cancer patients: Experience from the SEER database

Abstract: Background Complete axillary lymph node dissection (ALND) after a positive sentinel lymph node biopsy (SLNB) remains the standard practice. As nodal surgery has long been considered a staging procedure without a clear survival benefit, the need for ALND in all patients is debatable. The purpose of this study was to examine differences in survival for patients undergoing SLNB alone versus SLNB with complete ALND.

Prognostic value of the lymph node ratio in stage III colorectal cancer: a systematic review.

Abstract: Background Although nodal invasion represents one of the most powerful prognostic indicators in colorectal cancer, marked heterogeneity exists within stage III patients. Recently, the lymph node ratio (LNR), defined as the ratio of the number of positive nodes over the total number of examined nodes, was proposed to stratify outcome in stage III patients.

Prognostic impact of perioperative serum CA 19-9 levels in patients with resectable pancreatic cancer.

Abstract: Background Pancreatic cancer is one of the most deadly cancers, and serum carbohydrate antigen 19-9 (CA19-9) level has been reported to be a useful prognostic marker in pancreatic cancer. The purpose of this study was to determine which prognostic factor (preoperative or postoperative serum CA19-9 level) is more useful.

Chordoma of the mobile spine and sacrum: a retrospective analysis of a series of patients surgically treated at two referral centers.

Abstract: Chordoma is a rare tumor, and its natural history is still not well known. All patients affected by localized chordoma surgically treated at Istituto Ortopedico Rizzoli, Bologna, and Istituto Nazionale Tumori, Milan, Italy, between 1980 and 2008 were reviewed. Local recurrence, distant metastasis, and overall survival (OS) were analyzed both from time of diagnosis and from time of local recurrence/distant metastasis. A multivariable analysis to identify independent prognostic factors was carried out. A total of 138 consecutive patients were identified (sacrum 78%, lumbar spine 15%, cervical-dorsal spine 7%). Of these, 130 underwent surgical resection. Median follow-up was 142 months. The 5- and 10-year OS, local relapse-free survival (LRFS), and distant relapse-free survival (DRFS) were, respectively, 78% and 54%, 52% and 33%, and 86% and 72%. Size was an independent prognostic factor for OS (P value < .001), LRFS (P value: .038), and DRFS (P value: .004), while surgical margins independently predicted LRFS (P value: .003) with a trend for OS. The 5- and 10-year OS, LRFS, and DRFS after the first local relapse were 50% and 26%, 47% and 31%, and 64% and 61%. The size of the recurrence and quality of surgical margins did not influence postrelapse OS. The 5-year OS after the second local relapse was 19%. 22% of patients developed distant metastases with a 5-year post-metastases OS of 33%. Tumor size and surgical margins affected outcome only on initial presentation. However, wide surgery was feasible in a minority of cases. Most patients died of local–regional disease even when metastases occurred. Indeed, long-term prognosis was such that disease-free survival at 10 years was only 26%.
