AbstractOnly a minority of cases of differentiated thyroid carcinoma (DTC) have a poor clinical outcome. Clinical outcomes and molecular aspects were assessed in: 144 DTC ≤ 40 mm without distant metastases (group 1); 50 DTC > 40 mm without distant metastases (group 2); and 46 DTC with distant metastases (group 3). Group 3 had a worse outcome than the other two groups: during the follow-up, patients more frequently had persistent disease, died, or underwent further treatment. The outcomes did not differ between groups 1 and 2. Group 3 had a higher prevalence of TERT promoter mutations than group 2 (32.6% vs 14%). Group 1 had a higher frequency of BRAF mutations than groups 2 or 3 (61.1% vs 16.0% and 26.1%, respectively), while RAS mutations were more common in group 2 than in groups 1 and 3 (16.0% vs 2.1% and 6.5%, respectively). Groups 1 and 2 shared the same outcome, but were genetically distinct. Only lymph node involvement, distant metastases, older age and (among the molecular markers) TERT promoter mutations were independent predictors of a worse outcome. Metastatic DTC had the worst outcome, while the outcome was identical for large and small non-metastatic DTC, although they showed different molecular patterns. TERT promoter mutations emerged as an independent factor pointing to a poor prognosis.

Abstract To evaluate our diagnostic and therapeutic guidelines, clinical and long-term follow-up data of 219 patients with primary or secondary cutaneous CD30+ lymphoproliferative disorders were evaluated. The study group included 118 patients with lymphomatoid papulosis (LyP; group 1), 79 patients with primary cutaneous CD30+ large T-cell lymphoma (LTCL; group 2), 11 patients with CD30+ LTCL and skin and regional lymph node involvement (group 3), and 11 patients with secondary cutaneous CD30+ LTCL (group 4). Patients with LyP often did not receive any specific treatment, whereas most patients with primary cutaneous CD30+ LTCL were treated with radiotherapy or excision. All patients with skin-limited disease from groups 1 and 2 who were treated with multiagent chemotherapy had 1 or more skin relapses. The calculated risk for systemic disease within 10 years of diagnosis was 4% for group 1, 16% for group 2, and 20% for group 3 (after initial therapy). Disease-related 5-year-survival rates were 100% (group 1), 96% (group 2), 91% (group 3), and 24% (group 4), respectively. The results confirm the favorable prognoses of these primary cutaneous CD30+ lymphoproliferative disorders and underscore that LyP and primary cutaneous CD30+ lymphomas are closely related conditions. They also indicate that CD30+ LTCL on the skin and in 1 draining lymph node station has a good prognosis similar to that for primary cutaneous CD30+ LTCL without concurrent lymph node involvement. Multiagent chemotherapy is only indicated for patients with full-blown or developing extracutaneous disease; it is never or rarely indicated for patients with skin-limited CD30+ lymphomas.

Background: Non-small cell lung cancer (NSCLC) accounts for approximately 80% of new diagnoses of pulmonary carcinoma. This study investigated the correlation between 18 F-fluorodeoxyglucose uptake in computerized tomography integrated positron emission tomography and tumor size, lymph node metastasis, and distant metastasis in patients with NSCLC.Methods: The records of 318 NSCLC patients (220 male, 98 females; mean age 60.94 years) were evaluated retrospectively.Results: 278 cases were adenocarcinomas; 28 squamous cell carcinomas; and 12 large cell carcinoma. When the cases were categorized according to tumor size (group 1, ≤3 cm; group 2, >3 and ≤5 cm; group 3, >5 cm), the maximum standardized uptake value (SUVmax) was significantly lower in groups 1 and 2 compared with group 3 (p<0,001 for each). Considering all cases, tumor SUVmax was not correlated with age, gender or histopathological type. Lymph node metastases were seen in 250 cases: 80.2% of these were adenocarcinomas, 71.4% squamous cell carcinomas, and 58.3% large cell carcinomas. Neither lymph node involvement nor distant metastases were correlated with tumor SUVmax, although lymph node size was positively correlated with lymph node SUVmax (r=0.758; p<0.001).Conclusions: SUVmax was significantly associated with tumor size, but not with distant metastases or lymph node involvement. Therefore, SUVmax on positron emission tomography is not predictive of the presence of metastases.

From January 1975 to December 1991, 34 patients with a diagnosis of epithelial ovarian tumors of low malignant potential (LMP) were admitted to the Istituto Nazionale Tumori of Milan. Eighteen of them (group 1) underwent complete staging laparotomy and retroperitoneal para-aortic and pelvic lymphadenectomy, as for ovarian cancer. In the remaining 16 cases (group 2), the surgical treatment ranged from unilateral oophorectomy to incomplete staging procedure. In group 1, nine patients (50%) were found to have retroperitoneal nodal involvement. In group 2, all patients had stage I disease. Patients were followed up for 20–222 months (mean 108, median 86). There were two recurrences in group 2 (after 5 years) and none in group 1 (NS). Currently all patients are alive and disease free. Nine of 18 group 1 patients were upstaged to stage III on the basis of lymph node involvement only. However, at least in this retrospective series, lymph node metastases did not affect prognosis or survival.

Summary Objective: Dosimetry studies have shown that activities of 131I as small as 10-20 MBq may cause a stunning effect. A result of this stunning effect may be a lower success rate of the ablative 131I therapy for differentiated thyroid carcinoma (DTC). The aim of this study was to determine whether pre-therapeutic uptake measurement with 40 MBq 131I causes a lower success rate of ablation. Design: retrospective chart review study. Patients, methods: In two hospitals the ablation protocols differed in one respect only: in the one hospital no diagnostic 131I was applied before ablation (group 1, n = 48), whereas in the other hospital a 24-h uptake-measurement with 40 MBq 131I was performed (group 2, n = 51). Included were all DTC patients without distant metastases who had undergone 131I ablation between July 2002 and December 2005, and who had returned for 131I follow-up. Successful ablation was defined as absence of pathological 131I uptake on diagnostic whole-body scintigraphy and undetectable thyroglobulin-levels under TSH stimulation. Results: Overall, ablation was successful in 31/48 patients (65%) in group 1 and in 17/51 patients (33%) in group 2 (p=0.002). Multivariate analysis showed that pre-therapeutic uptake measurement using 40 MBq 131I was an independant determinant for success of ablation (p = 0.002). Conclusions: After applying a diagnostic activity of 40 MBq 131I before ablation, the success rate of ablation is severely reduced. Consequently, the routine application of 131I for diagnostic scintigraphy or uptake measurement prior to 131I ablation is best avoided.

ObjectiveWhether lymph-node dissection (LND) influences the lymph-node recurrence (LNR) risk in patients with papillary thyroid cancer remains controversial. The prognostic impact of macroscopic and microscopic lymph-node involvement at diagnosis is also an unresolved issue. A retrospective study was conducted to assess the influence of various LND procedures and to search for LNR risk factors.MethodsOverall 545 patients without distant metastases prior to surgery and main tumour ≥10 mm were included. A total thyroidectomy was performed in all patients with either no LND (Group 1,n=161), bilateral LND of the central and lateral compartments (Group 2,n=181) or all other dissection modalities (Group 3,n=203). Post-operative radioiodine was given to 496 (91%) patients. The 10-year cumulative probability of LNR was assessed and a prognostic study using multivariate analysis was performed.ResultsMacroscopic lymph-node metastases were present in 118 patients, 57 diagnosed before surgery and 61 only at surgery (including 81% in the central compartment). Overall, the 10-year cumulative probability of LNR was 7%. Macroscopic lymph-node metastases (P=0.001), extra-thyroidal invasion (P=0.017) and male gender (P=0.05) were independent risk factors, while bilateral LND of the central and lateral compartments was protective (P=0.028). In patients with macroscopic lymph-node metastases, the 10-year probability was lower in Group 2 than in Group 3 (10% vs 30%,P<0.01). In patients without macroscopic lymph-node metastases (n=427), no significant differences were observed between the three LND groups.ConclusionsPatients with macroscopic, but not microscopic, lymph-node involvement have a major LNR risk and need an optimal LND at primary surgery.

This study aims to review the safety of thyroidectomy combined with cervical neck dissection without drainage in well-differentiated thyroid carcinoma (WDTC). The medical records of consecutive patients who underwent thyroidectomy without drainage for WDTC were retrospectively reviewed. Group 1 included 123 patients who underwent thyroidectomy with central neck dissection and Group 2 included 46 patients who underwent thyroidectomy with central and lateral neck dissection. One hundred twenty-seven patients underwent thyroidectomy without neck dissection and were included in Group 3. Overall, 16 patients (5%) developed postoperative hematoma and/or seroma, seven patients (6%) in the Group 1, three patients (7%) in the Group 2, and six patients (5%) in Group 3. All patients had minor bleeding or seroma not requiring surgical intervention. Overall, 68 patients (23%) had transient postoperative hypocalcaemia, and four patients(l%) had permanent hypoparathyroidism. Seventeen patients (6%) had transient postoperative hoarseness and three had permanent vocal cord paralysis (0.6%). The postoperative stay for all groups was 1 day in 91 per cent of the cases. Patients from Groups 1 and 2 had no increased perioperative local complications or length of stay as compared with Group 3. Cervical neck dissection and thyroidectomy without drains is safe and effective in the treatment of WDTC.

19003 Background: Most clinical trials with adjuvant therapy in melanoma concentrate on high-risk patients including those with metastases to regional lymph nodes (LN), stage III and locally advanced T4, i.e., stage IIB and IIC. These trials may be missing the advantageous results in the relatively earlier stages. Methods: We reviewed the new American Joint Committee on Cancer (AJCC) for cancer staging of cutaneous melanoma and Balchs’ data for the prognostic factors. The data was correlated to patients’ survival expressed by the natural history of the disease. Results: We grouped the reported survival data into 3 risk groups, excluding patients with distant metastases. Group 1: 2–4mm deep primary with ulceration, >4mm deep primary without ulceration, micrometastases to 1–3 LN, primary not ulcerated; Group 2: >4mm deep primary with ulceration, micrometastases to 1–3 LN ulcerated primary, macrometastases to 1–3 LN, primary not ulcerated intransit metastases/satellitosis, without LN metastases; Group 3: macrometastases to 1–3 LN, ulcerated primary, metastases to 4 or more LN, matted LN, and/or intransit, metastases/satellitosis with LN metastases. The table summarizes the results. Conclusions: 1. Over one-third of the patients in group 1 died of disease in the first 5 years. They should be considered at intermediate risk and should receive adjuvant therapy. 2. Patient prognosis should determine the intensity of target therapy utilized in the adjuvant arena. While anti-CTLA-4 may be sufficient for group 1, the addition of anti-kinases may be required in group 2 and more so in group 3. [Table: see text] No significant financial relationships to disclose.

Background: Non-small cell lung cancer (NSCLC) accounts for approximately 80% of new diagnoses of pulmonary carcinoma. This study investigated the correlation between 18 F-fluorodeoxyglucose uptake in computerized tomography integrated positron emission tomography and tumor size, lymph node metastasis, and distant metastasis in patients with NSCLC. Methods: The records of 151 NSCLC patients (139 male, 12 female; mean age 59.60 years) were evaluated retrospectively. Results: Forty-one cases were adenocarcinomas; 45 squamous cell carcinomas; and 65 unspecified NSCLC. When the cases were categorized according to tumor size (group 1, ≤ 3 cm; group 2, > 3 and ≤ 5 cm; group 3, > 5 cm), the maximum standardized uptake value (SUVmax) was significantly lower in groups 1 and 2 compared with group 3 (p = 0.006 for each). Considering all cases, tumor SUVmax was not correlated with age, gender, or histopathological type. Lymph node metastases were pathologically proven in 24 cases: 24% of these were adenocarcinomas, 6% squamous cell carcinomas, and 16% unspecified NSCLC. Neither lymph node involvement nor distant metastases were correlated with tumor SUVmax, although lymph node size was positively correlated with lymph node SUVmax (r = 0.775; p < 0.001). Conclusions: SUVmax was significantly associated with tumor size, but not with distant metastases or lymph node involvement. Therefore, SUVmax on positron emission tomography is not predictive of the presence of metastases.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.
