The objective of the current study was to determine the significance of sarcomatoid differentiation as a prognostic factor for immunotherapy in metastatic renal cell carcinoma (RCC). ⋯ Our findings suggest that sarcomatoid differentiation is an important prognostic factor for immunotherapy in metastatic RCC.

Carcinoma of the ampulla of Vater has a relatively higher resection rate, lower recurrence rate, and more favorable prognosis than other malignant tumors of the periampullary region. Because of the relative low incidence of carcinoma of the ampulla of Vater, there have been few reports on the patterns and risk factors of recurrence after curative resection. The aim of this study was to evaluate the patterns and risk factors of recurrence after curative resection of ampulla of Vater carcinoma. ⋯ Lymph node metastasis is the most important risk factor for recurrence after a curative resection. Also, the fact that a higher probability of recurrence is anticipated in cases of ulcer formation and poorly differentiated tumors, there exists a need for a close-up follow-up program.

Prognostic indicators for patients with distal cholangiocarcinoma have not been confirmed because of its rarity. The aim of this study was to identify useful prognostic factors in patients undergoing surgical resection for distal cholangiocarcinoma. ⋯ These results suggest that lymph node metastasis and positive surgical margin as determined by surgical resection might be useful in predicting post-surgical outcome in patients with distal cholangiocarcinoma.
