RESUMO
OBJECTIVE: To examine the effect of S-1 adjuvant chemotherapy on muscle volume after curative gastrectomy in gastric cancer patients. PATIENTS: Forty-eight gastric cancer patients (31 men and 17 women) who underwent curative gastrectomy (distal gastrectomy: n=37, and total gastrectomy: n=11) between April 2010 and July 2011 were enrolled in this study. Sixteen patients underwent S-1 adjuvant chemotherapy (S-1 group) for 1 year after the operation, and 32 patients did not (NT group). METHODS: The psoas muscle areas were measured at the fourth lumbar vertebrae on CT images obtained before the operation, and at 6, 12, and 24 months after the operation. Muscle areas was statistically examined by comparing the preoperative and postoperative ratios. RESULTS: The muscle areas 12 months after the operation decreased to 0.86 ± 0.11 in the S-1 group and to 0.96 ± 0.08 in the NT group (p<0.05), and the significant difference disappeared at 24 months (0.93 ± 0.10 vs. 0.93 ± 0.11, NS). In the patients who underwent distal gastrectomy, the muscle areas decreased to 0.90 ± 0.05 in the S-1 group and to 0.96 ± 0.09 in the NT group at 12 months (p<0.05). Meanwhile, in those who underwent total gastrectomy, the muscle areas decreased to 0.80 ± 0.15 and 0.93 ± 0.03, respectively (NS). CONCLUSIONS: S-1 adjuvant chemotherapy affected muscle volume loss after gastrectomy in the gastric cancer patients, but the patients recovered from the adverse effect by 12 months after chemotherapy.

We experienced a rare case of delayed tracheal rupture after thyroidectomy for papillary thyroid cancer, and the infection causing sternomyelitis. A 69-year-old man presented subcutaneous emphysema after 6 days of total thyroidectomy with bilateral cervical and mediastinal dissection for lymph node metastases by adverse T sternotomy. He underwent tracheostomy on 10th postoperative day (POD), debridement of sternum on 14th POD, and implantation of skin-muscle flap using pectolaris major on 43th POD. The flap showed good adaptation and no infectious complications recurred, so that he could consequently receive closing procedure of tracheostomy on 94th POD.

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. We organized a radical operation even though the node status was classified to cStage IV, because ipsilateral axillary lymph nodes may be regarded as regional nodes for tumors invading the chest wall. Right upper lobectomy and chest wall resection were performed, and the ipsilateral hilar, mediastinal, and axillary lymphnode were dissected. Pathological findings showed no active cancer cell in the primary lesion and hilar lymph nodes(Ef. 3), but obvious metastasis in one of the axillary lymph nodes(pT0N0M1b, pStage IV). The patient received adjuvant chemotherapy(CDDP/vinorelbine), and is alive and tumor-free 10months after the resection.
