[Recurrence of Jejunal Carcinoma in the Ileum and Ovary - A Case Report].

Small bowel carcinoma has poor prognosis. The basis of treatment is surgical resection. There are no established guidelines for chemotherapy. We report a case in which we performed surgical resection of recurrent jejunal carcinoma. A 62-year-old woman underwent laparoscopic partial resection of the small intestine for primary jejunal carcinoma. The final diagnosis was T3N0M0, fStage II A. After 16 months of follow-up, she developed abdominal pain and vomiting. We diagnosed recurrence of jejunal carcinoma in the ileum and right ovary. Single-port laparoscopic small intestinal resection and right ovariectomy were performed. The patient underwent curative resection for recurrent lesions. The type of tumor in the ileum and right ovary was consistent with primary jejunal carcinoma by histopathological examination, and was diagnosed as recurrence of jejunal carcinoma. She is now on adjuvant chemotherapy with XELOX.

Modified selection criteria for complete cytoreductive surgery plus HIPEC based on peritoneal cancer index and small bowel involvement for peritoneal carcinomatosis of colorectal origin.

BACKGROUND: Complete cytoreductive surgery (CCRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) is on the verge of becoming the gold standard treatment for selected patients presenting peritoneal metastases (PM) of colorectal origin. PM is scored with the peritoneal cancer index (PCI), which is the main prognostic factor. However, small bowel (SB) involvement could exert an independent prognostic impact. AIM: To define an adequate cut-off for the PCI and to appraise whether SB involvement exerts an impact on this cut-off. PATIENTS AND METHODS: Patients (n = 139) treated with CCRS plus HIPEC were prospectively verified and retrospectively analyzed. One hundred presented with SB involvement of different extents and at different locations. RESULTS: All the patients with a PCI ≥ 15 exhibited SB involvement. Five-year overall survival was 48% when the PCI was <15 vs 12% when it was ≥ 15 (p < 0.0001. The multivariate analysis retained two prognostic factors: PCI ≥ 15 (p = 0.02, HR = 1.8), and the involvement of area 12 (lower ileum) (p = 0.001, HR = 3.1). When area 12 was invaded, it significantly worsened the prognosis: 5-year overall survival of patients with a PCI <15 and area 12 involved was 15%, close to that of patients with a PCI ≥ 15 (12%) and far lower than that of patients with a PCI <15 and no area 12 involvement (70%). CONCLUSION: A PCI greater than 15 appears to be a relative contraindication for treatment of colorectal PM with CCRS + HIPEC. Involvement of the lower ileum is also a negative prognostic factor to be taken into consideration.

Laparoscopic hemicolectomy for cutaneous malignant melanoma metastasis to the ileocaecal valve.

Colonic tumours are most frequently primary and lesions secondary to metastasis are uncommon. Malignant melanoma is an aggressive cancer, with a tendency to metastasize and recur. This report describes the case of a 66-year-old man who underwent wide local excision and adjuvant therapy for malignant melanoma three years prior to presentation with loose stools, abdominal cramps and iron deficiency anaemia. CT colonography showed a 6cm ileocaecal mass, and following a laparoscopic right hemicolectomy, histological examination revealed a metastatic melanoma to the ileocaecal valve. Subsequent positron emission tomography showed no residual metastatic disease. Malignant melanoma metastasis to the colon is a rare clinical entity. Metastectomy via laparoscopic right hemicolectomy is an appropriate and effective treatment.

Squamous cell carcinoma arising in an ovarian mature cystic teratoma: a case report.

Malignant transformation in a mature cystic teratoma of the ovary is rare. The most common malignancy is squamous cell carcinoma, which consists of about 75% of malignant transformations. In the present report, we describe a case of advanced-stage squamous cell carcinoma arising in a mature cystic teratoma. A postmenopausal 63-year-old woman with squamous cell carcinoma arising in a mature cystic teratoma is presented. The initial investigation by ultrasound showed a left adnexal mass with mixed echo pattern, which arose the suspension of malignancy. She underwent a laparotomy and left oophorectomy. Histopatholog was compatible with squamous cell carcinoma arising in a mature cystic teratoma. After a few episodes of intestinal obstruction and colostomy, she underwent partial resection of the ileum and sigmoid colon four months after the initial oophorectomy. Histopathologic study showed metastatic poorly-differentiated squamous cell carcinoma. Subsequently, she underwent two courses of combination chemotherapy with cisplatin, leucovorin, and 5-fluorouracil with no response. She died from progression of the disease nine months after the initial operation.

[A case of widespread ileal stenosis caused by metastatic disseminated peritoneal carcinomatosis from lung cancer resected 8 years previously].

A 46-year-old man was admitted because of ileus. He had undergone an operation for lung carcinoma (stage IA) 8 years previously in another hospital. Because small bowel enema study showed widespread stricture of the ileum, we performed an operation. During the operation we diagnosed metastatic small bowel carcinoma. Because the resected sample of the small bowel carcinoma was similar to the lung carcinoma pathologically and detailed examination after the operation showed no other neoplasm, we considered this case to be small bowel metastasis of the lung carcinoma resected 8 years previously.
