Clinical Trial Controlled Clinical Trial
The clinical efficacy of neoadjuvant chemotherapy in squamous esophageal cancer: a prospective nonrandomized study of pulse and continuous-infusion regimens with Cisplatin and 5-Fluorouracil.
We evaluated cisplatin and 5-fluorouracil as preoperative adjuvant chemotherapy for patients with locally advanced squamous esophageal cancer and compared two different infusion regimens. The outcomes were also compared with those of our historical control patients treated by surgery alone. ⋯ Preoperative adjuvant chemotherapy with cisplatin and 5-fluorouracil infusion, in pulse or continuous regimens, followed by surgery for squamous esophageal cancer patients had no added benefit in the overall survival.

Comparative Study
Positron emission tomography is superior to computed tomography for metastatic detection in melanoma patients.
Whole-body positron emission tomography (PET) provides diagnostic information not currently available with traditional imaging and may improve the accuracy of staging melanoma patients. ⋯ PET is more sensitive and specific than CT for detection of melanoma metastasis and should be considered the primary staging study for recurrent disease. PET shows greater ability to detect soft tissue, small-bowel, and lymph node metastasis that do not meet criteria designated as abnormal by CT. PET is superior to CT even when sites not routinely evaluated by CT are excluded from comparative analysis.

We prospectively compared the sensory morbidity and lymphedema experienced after sentinel node biopsy (SLNB) and axillary dissection (ALND) over a 12-month period by using a validated instrument. ⋯ Among women undergoing breast-conserving therapy, SLNB has significant sensory morbidity, although approximately half that of ALND. Sensory morbidity improves in the first 3 months after surgery, but patients continue to report sensory morbidity at 1 year. Longitudinal follow-up is required to further assess lymphedema.
