Comparative Study Clinical Trial
Why do patients with low-grade soft tissue sarcoma die?
The patterns of failure and mechanisms of sarcoma-specific death are poorly characterized among the minority of patients with low-grade soft tissue sarcoma (STS) who succumb to disease. ⋯ Among patients with low-grade STS, DOD occurs in approximately 9% of patients. Nonextremity site, larger size, and less than R0 resection are the most important risk factors for DOD, and distinct patterns of recurrence and death are predicted by primary tumor site.

Carcinomatosis of colorectal origin is increasingly treated by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CS-HIPEC). This procedure commonly involves multivisceral resection (MVR) with potentially high morbidity. We analyzed the effect of MVR on the outcome after CS-HIPEC. ⋯ Increased risk of complications is associated with the number of intestinal anastomoses, but not with multivisceral resection in CS-HIPEC. Long-term survival is not affected by the number of resected organs.

The treatment of massive and/or symptomatic pericardial effusion in patients with cancer remains a subject of discussion. Medical and surgical management have been proposed. In the present study, we aimed to determine the prognostic factors influencing survival of cancer patients admitted in intensive care unit (ICU) with severe pericardial effusion to better select the treatment strategies. ⋯ In this series of patients presenting with severe pericardial effusion, the control of the underlying neoplasm was the only significant factor influencing survival and could be helpful in making decision to the optimal (invasive) treatment that should balance treatment efficacy with life expectancy.

Multicenter Study
Age-, race-, and ethnicity-related differences in the treatment of nonmetastatic rectal cancer: a patterns of care study from the national cancer data base.
Recent studies suggest that older patients and minorities are less likely to receive surgical and adjuvant therapy for rectal cancer. We analyzed the independent effect of age and race/ethnicity on treatment for rectal cancer controlling for comorbidity and socioeconomic status using a nationwide sample ⋯ A high proportion of older patients with rectal cancer do not receive appropriate surgical or adjuvant therapy, even when controlling for comorbidity. African American patients are also less likely to undergo resection, but are equally likely to undergo sphincter preservation and adjuvant therapy compared with whites. Efforts are needed to uncover the root causes underlying these observations and optimize treatment of rectal cancer.

Preoperative diagnosis of pancreatic cystic neoplasms is problematic. We evaluated our experience with endoscopic ultrasound (EUS) to determine the utility of fine-needle aspiration cytology (FNAC) in surgical decision-making. ⋯ The decision to proceed with nonoperative management should not be based on a negative or nondiagnostic FNAC alone, as 67% of negative and 92% of nondiagnostic specimens were associated with malignant or premalignant pathology.
