Short-Term Outcomes from a Randomized Screening Phase II Non-inferiority Trial Comparing Omentectomy and Omentum Preservation for Locally Advanced Gastric Cancer: the TOP-G Trial.

Background: Omentectomy is considered an essential part of curative gastrectomy for locally advanced gastric cancer (GC), albeit without solid evidence. We conducted a randomized phase II trial (the TOP-G trial) comparing omentectomy and omentum preservation for gastric cancer. This report describes the short-term findings regarding the trial's secondary endpoints.

Perianal metastasis of non-small cell lung cancer.

We herein present the case of a 36-year-old woman who developed perianal metastasis of non-small cell lung cancer that was diagnosed based on the presence of symptoms mimicking a hemorrhoid. The patient initially underwent radiotherapy for a left superior sulcus tumor, then subsequently complained of a perianal mass that had prolapsed and bled. The tumor was removed via resection.

[A case of postmenopausal breast cancer becoming HER2 positive after neoadjuvant hormone therapy].

A 75-year-old woman presented to a local doctor with a lump in the right breast. On physical examination, a tumor measuring 24mm was palpable in the BD area of her right breast. Mammography showed category 5 disease, and ultrasonography revealed a tumor measuring 24×16 mm.

Phase II study on the combination of irinotecan plus cisplatin as a second-line therapy in patients with advanced or recurrent gastric cancer.

A pilot phase II study was conducted to evaluate the efficacy and safety of the combined administration of irinotecan (CPT-11) plus cisplatin (CDDP) as a second-line therapy for advanced or recurrent gastric cancer. Between November, 2006 and May, 2009, 18 patients were enrolled in this study. The patients were required to have received prior chemotherapy with S-1 (n=17), an orally administered 5-fluorouracil (5-FU) prodrug, or S-1 plus CDDP (n=1).

[Three patients with local recurrence of ER-positive breast cancer for whom anastrozole was clinically effective].

We treated three postmenopausal female patients with unresectable local recurrence from breast cancer. All pathological diagnoses of the local recurrence lesions were ER-positive breast cancer. For treatment, we administered anastrozole to these three patients.

[Multiple hepatic metastases and ovarian metastases of colon cancer responding to combined therapy with S-1 and CPT-11--a case report].

We report a patient with multiple hepatic metastases and ovarian metastases of transverse colon cancer treated by combination of S-1 and CPT-11. The patient was a 51-year-old woman with cancer of the transverse colon and multiple hepatic metastases. She had undergone surgery.

[An institution-randomized trial of 5-fluorouracil and l-leucovorin therapy given monthly versus every two months to patients with advanced colorectal carcinoma].

The aim of this study was to evaluate the efficacy and toxicity of 5-fluorouracil (5-FU) and l-leucovorin (l-LV) given at the same dose intensity and administered monthly (given weekly for 3 weeks followed by a week of rest; arm A) or every 2 months (given weekly for 6 weeks followed by 2 weeks rest; arm B) to patients with advanced colorectal carcinoma. The dose of 5-FU was 500 mg/body or 750 mg/body, with an average dose of 432.8 mg/m2.
