Our study suggests considerable disagreement among pathologists on the diagnosis of melanoma versus other pigmented lesions. Tumor thickness and presence of ulceration are the most reproducible histologic features of cutaneous melanoma.

No significant difference was found in both patient groups regarding postoperative mortality and complications, biliary complications, and especially cystic duct leaks. A retrospective comparison of literature data showed that use of ultrasonic dissection during LC seems to reduce the risk of BDI. Nevertheless, a learning curve in the use of ultrasonic-activated devices is required: a significant differences in postoperative major complications and biliary complications between the expert and the surgeon-in-training subgroups was shown. Furthermore, ultrasonic scissors misuse may cause bowel injuries in patients with severe adhesions, and this could represent a possible limitation for surgical safety.

We consider our findings as a novelty and signal the possible existence of a clinical syndrome. Five of a total of 21 previously reported cases in the literature were also described as being associated with other cancers (non-Hodgkin's lymphoma in two cases, two not further specified tumors of the liver and brain, an epithelial ovarian cancer, and a non-small cell lung cancer in one case each). Close follow-up and careful investigation in search of a second visceral neoplasm are strongly recommended in cases of LCA, but further clinical observations and more in-depth genetic and molecular studies are needed before any valid conclusions can be drawn.

BACKGROUNDNeoadjuvant chemotherapy for patients with muscle‐invasive bladder carcinoma is given to treat micrometastases and to preserve the bladder. The objective of this study was to evaluate the possibility of bladder preservation in patients with muscle‐invasive bladder carcinoma who were treated with neoadjuvant methotrexate, vinblastine, doxorubicin, and cisplatin (M‐VAC) chemotherapy.METHODSOne hundred four consecutive patients with T2–T4,N0,M0 transitional cell carcinoma of the bladder were treated with 3 cycles of neoadjuvant M‐VAC chemotherapy. After clinical restaging, 52 patients underwent transurethral resection of the bladder (TURB) alone, 13 patients underwent partial cystectomy, and 39 patients underwent radical cystectomy.RESULTSThe median survival for the entire group was 7.49 years (95% confidence interval, 4.86–10.0 years). Forty‐nine patients (49%) were T0 at the time of TURB after receiving M‐VAC. Thirty‐one of 52 patients (60%) who received chemotherapy and underwent TURB alone were alive at a median follow‐up of 56 + months (range, 10–160 + months): Twenty‐three patients (44%) in that TURB group maintained an intact bladder. Of 13 responding patients with monofocal lesions who underwent partial cystectomy, only 1 patient required salvage cystectomy, and survival generally was good. The 5‐year survival rate for this group was 69%. With a long median follow‐up of 88 + months (range, 16–158 months), 4 patients (31%) were alive with a functioning bladder. In the radical cystectomy group, the median follow‐up was 45 months (range, 4–172 + months), and 15 of 39 patients (38%) patients remained alive. In 77 patients who had their tumors down‐staged to T0 or superficial disease, the median follow‐up was 63 months (range, 4–172 + months), and the 5‐year rate survival was 69%. This is in contrast to a 5‐year survival rate of only 26% in 27 patients who failed to respond and had a status ≥ T2 after receiving chemotherapy (median follow‐up, 31 months; range, 7–156 + months). The median survival for 27 elderly patients (age ≥ 70 years; median age, 73 years; range, 70–82 years) was 90 months (7.5 years). For elderly patients who underwent TURB and partial cystectomy, the 5‐year survival rate was 67% with a 109‐month (9‐year) median survival; 47% of patients preserved their bladders intact. The median follow‐up of the living elderly patients was 61 months (range, 20–120 + months).CONCLUSIONSBladder sparing in selected patients on the basis of response to neoadjuvant chemotherapy is a feasible approach that should be confirmed in prospective, randomized trials. Selected elderly patients are candidates for this approach. Cancer 2003;97:1644–52. © 2003 American Cancer Society.DOI 10.1002/cncr.11232

Although ILC is more often multicentric, bilateral, and associated with a positive margin of resection, local control and survival are similar to IDC. ILC can be treated similarly to IDC with good results.

Extended needle biopsy significantly increases the accuracy of biopsy Gleason score for assessing final prostate cancer grade.

IE has acceptable sensitivity for lymph node macrometastases, but it is a weak tool for diagnosing micrometastases. FS and TP are roughly equivalent. IE allows management changes, because approximately 20% of all patients are expected to undergo synchronous axillary dissection, and it is particularly helpful in T2 patients. This may allow substantial cost savings for the health-care system.
