TL;DR: The study indicated that blood vessel invasion in the primary breast carcinoma is more significant than lymph node metastasis.
Abstract: Prognostic significance of blood vessel invasion in carcinoma of the female breast has been evaluated by study of 242 cases of radical mastectomy done at the Tata Memorial Hospital. The significance of axillary node involvement with the disease has been simultaneously evaluated. In the absence of blood vessel invasion and lymph node metastasis the 5 year survival rate was 98%. Compared with this, 5 year survival rate was reduced to 59% when the blood vessel invasion was present but no lymph node metastasis. Only 12% survived for 5 years when both blood vessels and lymph nodes were involved with the disease. The study indicated that blood vessel invasion in the primary breast carcinoma is more significant than lymph node metastasis.

TL;DR: This feature of the e antigen provides an assay system for laboratory diagnosis of potential clinical usefulness and suggests its possible role in pathogenesis of hepatocellular injury.
Abstract: Serums containing the "e" antigen of hepatitis B virus were subjected to electrophoresis in polyacrylamide gel. An extra band appeared in the lactate dehydrogenase isozyme pattern, but this band was undetectable in serums containing antibodies to the e antigenic determinant. Prior separation of the lactate dehydrogenase isozyme-5 fraction by chromatography of serum on minicolumns of diethylaminoethyl-Sephadex-A50 improved electrophoretic identification of the extra band. Neutralization with antibodies to the e antigen as well as by antibodies to the homologous d or y component of the hepatitis B surface antigen removed the extra band; antibodies to the lactate dehydrogenase isozyme-5 removed both the normal and the extra enzymatic band of isozyme-5. This feature of the e antigen provides an assay system for laboratory diagnosis of potential clinical usefulness and suggests its possible role in pathogenesis of hepatocellular injury.

TL;DR: It is found that patients in whom the lymph nodes were preserved had a better survival as compared to patients in which the lymph node were removed en bloc with the primary tumour.
Abstract: This study was undertaken to find out if there are any factors of prognostic significance that can help the surgeon in the management of osteogenic sarcoma. One hundred and thirty-nine cases of osteogenic sacrocma were treated during a 30-year period and their survival figures have been analysed with respect to age, sex, extent of disease, previous treatment, and value of lymphadenectomy. We found that patients in whom the lymph nodes were preserved had a better survival as compared to patients in whom the lymph nodes were removed en bloc with the primary tumour. This further supports our contention that the regional lymph nodes have an important role to play in the immune response against osteosarcoma. The experimental work of the cytotoxic action of regional lymph node cells against osteosarcoma cell lines has been studied in our laboratory. The results of this study stimulated us to undertake this retrospective analysis.

TL;DR: The skin was the commonest site of a second cancer among colon cancer patients; the possible etiological association of these two cancers appears very intriguing.
Abstract: Incidence rate of colon cancer is low in India compared to the Western countries. The dietary habits may be the protective factor in our population. During a 32 year period (1941-1972), 555 cases of colonic cancer were recorded at the Tata Memorial Hospital, Bombay. Among the social groups utilizing this hospital, the Parsis (Zoroastrians) have the highest incidence of colonic cancer. The frequency of cancer of the caecum and sigmoid are almost equal. Cancer of splenic and hepatic flexures are predominantly seen in men. Of the resected cases 50% survived for 5 years and 40% for 10 years. When cancer was localised, the 5 year survival rate was 64%. The 5 year survival rate among transverse colon cancer patients was 70%. The skin was the commonest site of a second cancer among colon cancer patients; the possible etiological association of these two cancers appears very intriguing.

TL;DR: The histological appearance of the lymph nodes in cases of osteogenic sarcoma of the limb bones shows that regional lymph nodes play an important part in the immunological process and preservation of regional nodes is suggested.
Abstract: This paper presents the histological appearance of the lymph nodes in cases of osteogenic sarcoma of the limb bones. The nodes were studied for the degree of sinus histiocytosis. Cases with no sinus histiocytosis showed a poor prognosis while cases with moderate to marked sinus histiocytosis showed a better rate of survival. Since the regional lymph nodes play an important part in the immunological process, preservation of regional nodes is suggested.
