[Three cases of patients in their eighties who received anti-EGFR antibody mono-therapy as first-line treatment for metastatic colorectal cancer].

We report three cases of patients in their eighties who received anti-EGFR antibody mono-therapy as first-line treatment for metastatic colorectal cancer. CASE 1: An 86-year-old woman who received cetuximab after a colostomy for unresectable rectal cancer with synchronous liver and lung metastases. Serum levels of CEA and CA19-9 showed a significant decrease at 2 months, after which they showed a gradual increase. Computed tomography (CT) revealed a reduction in the rectal tumor. CASE 2: An 82-year-old woman who received cetuximab for peritoneal metastases after a transverse colectomy. Serum levels of CEA and CA19-9 decreased to normal levels at 2 months, and CT imaging revealed disappearance of the tumor in the peritoneal cavity. CASE 3: A 79-year-old man who received panitumumab for lung, liver and para-aortic lymph node metastases after a descending colectomy. Serum levels of CEA and CA19-9 showed a decrease at 1 month, after which they showed a gradual increase. No marked change in the tumor was observed by CT. No change was observed in performance status or Vulnerable Elders Survey( VES-13) score, and the effect on overall condition was minimal. Grade 1-2 acneiform skin rash, paronychia, and desquamation, and grade 2-3 dry skin and pruritis were observed. More precise instructions on measures for dealing with skin rash are necessary to obtain higher drug compliance.

Phonatory function following esophagectomy for esophageal cancer.

BACKGROUND/AIMS: Quality of life can be adversely affected in many patients who suffer phonation disorders such as hoarseness and dysphonia following esophagectomy. The present study investigated postoperative phonation disorders in 15 patients who underwent esophagectomy for esophageal cancer. METHODOLOGY: None of the patients had signs of hoarseness before or after surgery. Aerodynamic testing to assess phonatory function testing and laryngoscopy for observing laryngeal movements were performed before and after surgery. As a control, the same tests were conducted in 20 patients treated for gastric cancer by gastrectomy. RESULTS: For esophagectomy patients, mean postoperative flow rate was significantly increased and maximum postoperative phonation time was significantly decreased after operation. Laryngoscopy confirmed postoperative paralysis of left laryngeal movements and excessive adduction of the right, unaffected vocal cord during phonation in 8 of 15 esophagectomy patients, although hoarseness was not reported by any patient. No significant changes were observed for mean postoperative flow rate or maximum postoperative phonation time following surgery in gastrectomy patients. CONCLUSIONS: Surgical procedures in the vicinity of the recurrent laryngeal nerve appear to be the cause of postoperative phonation disorders in patients undergoing esophagectomy for esophageal cancer, and these disorders can occur in the absence of symptoms such as hoarseness and dysphonia.
