The Impact

Abstract Context: The impact of microscopic nodal involvement on the risk of persistent/recurrent disease (PRD) remains controversial in patients with papillary thyroid carcinoma (PTC). Objective: The goal of the study was to assess the risk of PRD and the 4-year outcome in PTC patients according to their initial nodal status [pNx, pN0, pN1 microscopic (cN0/pN1) or pN1 macroscopic (cN1/pN1)]. Design: We conducted a retrospective cohort study. Patients: The study included 305 consecutive PTC patients referred for radioiodine ablation from 2006 to 2011. Main Outcome Measure: We evaluated the risk of structural PRD and the disease status at the last follow-up. At ablation, persistent disease was consistently assessed by using post-radioiodine ablation scintigraphy combining total body scan and neck and thorax single-photon computed tomography-computed tomography (SPECT-CT) acquisition. Results: Of 305 patients, 128 (42%) were pNx, 84 (28%) pN0, 44 (14%) pN1 microscopic, and 49 (16%) pN1 macroscopic. The 4-year cumulative risk of PRD was higher in pN1 macroscopic than in pN1 microscopic patients (49% vs 24%, P = .03), and higher in pN1 microscopic than in pN0 (12%, P = .01) or pNx patients (6%, P < .001). On multivariate analysis, tumor size of 20 mm or greater [relative risk (RR) 3.4; P = .0001], extrathyroid extension (RR 2.6; P < .003), pN1 macroscopic (RR 4.5; P < .0001), and pN1 microscopic (RR 2.5; P < .02) were independent risk factors for PRD. At the last visit, the proportion of patients with no evidence of disease decreased from pNx (98%), pN0 (93%), and pN1 microscopic (89%) to pN1 macroscopic patients (70%) (P < .0001, Cochran-Armitage trend test). Extrathyroid extension (odds ratio 9.7; P < .0001) and N1 macroscopic (OR 4.9; P < .001) independently predicted persistent disease at the last visit, but N1 microscopic did not. Conclusions: Patients with microscopic lymph node involvement present an intermediate outcome between that observed in pN0-pNx patients and pN1 macroscopic patients. These data may justify modifications to the risk recurrence staging systems.

<p class="abstract"><strong>Background:</strong> Depth of invasion is included in the staging of oral cavity malignancies in the recent 8<sup>th</sup> edition of American Joint Committee on Cancer or tumour, node and metastasis staging system.

Positive margin is seen only in patients with tumour DOI more than 0.5 cm, more than 50% of deep tumours had close margins while 75% of superficial tumours had adequate margin. Out of the 24 T3 tumours in this study 13 were upstaged due to inclusion of DOI, which would have been T2 according to the previous staging system. There is 54.1% (13 out of 24) upstaging in T3 tumours (T2 to T3), 23% (3 out of 13) in T2 (T1 to T2). There is no significant correlation between DOI and anatomical site, tumour size, tumour thickness, lymphovascular invasion and grade.</p><p class="abstract"><strong>Conclusions:</strong> Depth of invasion in oral cavity malignancies impacts adversely lymph node metastasis and margin status.

4133 Background: Cholangiocarcinoma remains an orphan disease for which prospective studies are missing to evaluate the impact of systemic chemotherapy on survival. Methods: Univariate and multivariate analysis of parameters that might impact survival were analyzed in a cohort of 242 consecutive patients with cholangiocarcinoma treated in a single institution between 2000 and 2004. Variables were WHO performance status (PS), age, symptoms, tumor size, extent of the disease, lymph node involvement, site of metastasis, tumor markers, pathology, and type of treatment including surgery, chemotherapy and radiotherapy. Results: Statistically significant prognostic factors of survival in univariate analysis are displayed in the table : In multivariate analysis, PS, tumor size and surgery were independent prognostic factors. Subgroup analysis demonstrated that in patients with advanced diseases (lymph node involvement, peritoneal carcinomatosis and/or distant metastasis), patients who had no surgery benefited of chemotherapy (median survival 13.1 versus 7.4 months in patients with/without chemotherapy, p = 0.006). Moreover, survival was further improved when patients could benefit of chemotherapy following total and/or partial resection (median survival 22.9 versus 13.0 months in patients with/without chemotherapy, p = 0.03). Conclusions: This study strongly suggests the positive impact on survival of multimodality approaches including surgery and chemotherapy in patients with advanced cholangiocarcinoma.

A 37-year-old male case was admitted with goiter. Ultrasonography of thyroid showed a 5 cm cystic nodule in the left lobe with a 1.5 cm solid component. Fine needle aspiration biopsy revealed atypia of undetermined significance or follicular lesion. The patient was operated on. The pathological diagnosis was reported as papillary thyroid carcinoma. The immunohistochemical examination showed multiple foci of Langerhans cell histiocytosis involving both lobes. The patient died due to cardiac arrest with respiratory causes in the early postoperative period. Langerhans cell histiocytosis is a rare primary condition which involves abnormal clonal proliferation of Langerhans cells in various tissues and organs. Thyroid involvement is infrequently seen. Although the etiology is unknown, genetic components may be linked to the disease. It is also associated with a family history of thyroid disease. Papillary thyroid carcinoma is the most common malignant epithelial tumor of the thyroid gland. Langerhans cell histiocytosis presenting with papillary thyroid carcinoma is rare. The privilege of our case is langerhans cell histiocytosis of the thyroid with multiple cervical lymph node involvement accompanying cervical lymph node metastatic thyroid papillary carcinoma.
