Recombinant interleukin-2 (IL-2)/chemotherapy combinations have recently entered clinical trial. The rationale for sequencing has primarily been empiric or based on in vitro data. To establish in vivo models for chemoimmunotherapy trials, we investigated IL-2 alone and in combination with dacarbazine (DTIC) and adriamycin. IL-2 (as a single agent given i.v. at 1-3 x 10(5) Cetus units once daily...

BACKGROUND We reported our experience of adenocarcinoma of sigmoid colon neovagina. CASE PRESENTATION A 67-year-old female with a history of neovagina construction for Rokitansky syndrome complained of vaginal bleeding. She had a mucinous adenocarcinoma at the anterior aspect of the neovagina. Her original surgery, using sigmoid colon to construct the artificial vagina, was 40 years ago CON...

Deregulated microRNAs play a role in the development and progression of colon cancer, but little is known about their tissue and cell distribution in the continuum of normal mucosa through the premalignant adenoma to invasive adenocarcinoma. The aim of this study was to examine the expression pattern of the miR-17-92 cluster (miR-17, miR-18, miR-19, miR-20 and miR-92) as well as miR-21, miR-31,...

An admixture of hyperplastic and adenomatous components within the same polyp is unusual. Adenocarcinoma arising from a mixed hyperplastic/adenomatous polyp (MHAP) occurs even more rarely. We report the first case of a 59-year-old male who presented with invasive adenocarcinoma originating from a MHAP at a sigmoid colon and synchronous transverse colon cancer.

Metastatic tumors to the breast from colon adenocarcinoma are very rare. They are usually indicative of disseminated disease, and the prognosis is poor. Generally, radical operation should be avoided unless needed for palliation. This case report described a patient with breast metastasis from colon adenocarcinoma treated by simple mastectomy.

The caecum and the ascending colon are the colon segments most frequently affected by tumoral synchronism. Synchronous colorectal carcinoma etiopathogenesis is complex and most likely by malignancy of preexisting adenomas (adenoma-adenocarcinoma sequence). The following tumoral synchronism clinical case's particularity is represented by the simultaneous diagnosis of a flat-type adenocarcinoma o...

Colonic small cell carcinomas (SCCs) are rare, aggressive tumors characterized by early metastasis and poor prognosis. We describe a 39-year-old man with a history of ulcerative colitis and left colon adenocarcinoma resected at an outside institution who presented with hematochezia and proctalgia. Work-up revealed left colon SCC with liver metastases. After his excellent response to neoadjuvant...

A primary clear cell adenocarcinoma of the colon is a rare oncologic entity. The current study presents a case of such a tumor in the transverse colon of a 26-year-old male, and describes the computed tomography features of the neoplasm. The tumor appeared as an extensive extracolic mass, which displaced the loop of the small bowel and pancreas, and invaded the spleen. A laparotomy was performe...

A 67-year-old woman who was presented to the gynecologist with a two-month history of heavy vaginal bleeding, after an excisional biopsy of vulvar mass, was diagnosed with the right colon adenocarcinoma metachronous metastasis to the vulva. Pathological examination preliminarily revealed by primary adenosquamous carcinoma of vulva. The original submitting pathologist and gynecologist were conta...
