[Effect of Post-Gastrectomy Adjuvant S-1 Chemotherapy on Muscle Volume in Gastric Cancer Patients].

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).

[Sternomyelitis caused by delayed tracheal necrosis after thyroidectomy;treatment using muscle flap of petoralis major].

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.

[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.
