The clinical importance of a transcription reverse-transcription concerted (TRC) diagnosis using peritoneal lavage fluids in gastric cancer with clinical serosal invasion: a prospective, multicenter study.

Purpose: We have developed a novel molecular method of diagnosis using the technique of transcriptase-reverse transcriptase concerted reaction (TRC) for the detection of cancer micrometastasis. This study prospectively examined the clinical importance of the TRC diagnosis with peritoneal lavage fluids collected from gastric cancer operations at multiple institutes.

Methods: TRC amplification targeting carcinoembryonic antigen mRNA was applied to detect gastric cancer cells in peritoneal lavage fluids obtained during gastric cancer resections from nine different hospitals.

Pattern of abdominal nodal spread and optimal abdominal lymphadenectomy for advanced Siewert type II adenocarcinoma of the cardia: results of a multicenter study.

Background: It remains uncertain whether radical lymphadenectomy combined with total gastrectomy actually contributes to long-term survival for Siewert type II adenocarcinoma of the cardia. We identified the pattern of abdominal nodal spread in advanced type II adenocarcinoma and defined the optimal extent of abdominal lymphadenectomy.

Methods: Eighty-six patients undergoing R0 total gastrectomy for advanced type II adenocarcinoma were identified from the gastric cancer database of 4,884 patients.

[A radical resection of non-small cell lung cancer invading chest wall with ipsilateral axillary lymph node metastases].

A 41-year-old man who had non-small cell lung cancer invading his right 3rd, 4th and 5th ribs with hilum lymph node swelling(cT3N1M0, cStage III A), received chemoradiation therapy, cisplatin(CDDP)/docetaxel, and 2 Gy/Fr of irradiation prior to surgery. But the therapy was discontinued due to interstitial pneumonitis on day 24, during 28 Gy of radiation. At that time, a PET-CT scan revealed the accumulation of FDG in the primary tumor, hilar lymph node, and one of the ipsilateral axillar lymph nodes, in which cancer cell presence was proven by aspiration needle cytology.

[A phase I study of combination chemotherapy using TS-1 and weekly paclitaxel for advanced gastric cancer].

The safety of chemotherapy combining TS-1 and weekly paclitaxel for the treatment of unresectable and recurrent gastric cancer was evaluated in this study. Paclitaxel was administered by intravenous drip infusion at a starting dose (level 1) of 50 mg/m2 on days 1, 8, and 15. TS-1 was administered orally at a dose of 40 mg/m2twice a day for 2 weeks (days 1-14) followed by 2 weeks rest.
