Para-aortic lymph node metastasis in carcinoma of the distal bile duct

BACKGROUND/AIMS: Lymph node dissection plays an important role in radical surgery for pancreaticoduodenal carcinomas. The aim of this study was to identify the critical areas of lymph node dissection in carcinoma of the distal bile duct. METHODOLOGY: Between January 1995 and December 1996, 20 consecutive patients with distal bile duct cancer underwent pancreaticoduodenectomy with extended lymph node dissection (including the para-aortic nodes). Histopathologic findings were examined with special reference to lymph node metastasis. RESULTS: Histological evidence of lymph node metastasis was found in 11 patients (55%). The areas with frequent metastases were the posterior pancreaticoduodenal lymph nodes (35%), and the nodes around the hepatoduodenal ligament (35%) and around the common hepatic artery (30%). Para-aortic lymph node involvement was identified in 5 patients (25%). Most of these existed in the inter-aorticocaval space. Pancreatic parenchymal invasion was present in 10 patients. Half of the patients with pancreatic invasion had para-aortic nodal involvement. Para-aortic lymph node metastasis was significantly associated with pancreatic parenchymal invasion (p<0.05). CONCLUSIONS: In carcinoma of the distal bile duct with pancreatic parenchymal invasion, extended lymph node dissection (including para-aortic nodes) should be undertaken because of the relatively high incidence of metastasis.     

Bcl-xL overexpression restricts heat-induced apoptosis and influences hsp70, bcl-2, and Bax protein levels in FL5.12 cells

In 109 patients with epithelial ovarian cancer, 25 (23%) had pelvic lymph node (PLN) metastasis. Positive rates of PLN metastasis according to the clinical stage based on disease distribution except retroperitoneal lymph node were 2% for stage I, 6% for stage II, 44% for stage III, and 64% for stage IV. The nine disease sites, such as subdiaphragmatic surface, liver and spleen capsule, intestine and mesentery, omentum, pelvic peritoneum, sigmoid colon and rectum, uterus and tubes, peritoneal cytology, and paraaortic lymph node (PAN), were found to have a statistically significant relationship with PLN metastasis by univariate analysis. Multivariate analysis using a logistic regression model selected the omentum and PAN as independent factors with a statistical significance. The incidence of PLN metastasis in epithelial ovarian cancer with the above two parameters can be assumed to be greater than that without the two parameters by 42.6 times. The present data suggested that for the disease with PAN and/or omental metastasis, removal of the PLN may be mandatory from the standpoint of cytoreduction.     

Axillary node metastasis from T1N0M0 breast cancer: possible avoidance of dissection in a subgroup

BACKGROUND: Axillary lymph node dissection is now no longer considered to be the standard treatment in all patients with invasive breast cancer. We have attempted to identify a sub-group of patients with invasive breast carcinoma who may not need to undergo axillary lymph node dissection. METHODS: Patients (n = 823) with T1 N0M0 invasive breast cancer treated at our hospital between 1970 and 1994 were studied. We investigated the relationship between positive axillary lymph nodes and the following clinico-pathological factors: patient age, menopausal status, contralateral breast cancer (synchronous or asynchronous), tumor location, tumor size (T:cm), histopathology, histological grade, presence or absence of malignant microcalcification or spiculation on mammography and estrogen receptor status. RESULTS: The incidence of axillary lymph node metastases in patients with T1N0M0 invasive breast cancer was 25% (208/823). The node-negative group was significantly older than the node-positive group. Premenopausal patients had a higher rate of lymph node metastases although this was not significant. The frequency of nodal metastases when related to the tumor size was as follows: T< or =1.0 cm, 17%; T< or =1.5 cm, 25%; T< or =2.0 cm, 29%. Mammography revealed that patients with malignant calcification or spiculation had a significantly higher rate of nodal metastases than those without these findings. Certain tumor types (medullary, mucinous and tubular carcinomas) had lower positive rates for lymph node involvement. With regard to the histological grade, lymph node positivity increased significantly with high-grade tumors. No correlation was observed between any other factors and the presence or absence of lymph node metastases. CONCLUSIONS: It may be possible to avoid axillary lymph node dissection in postmenopausal patients (50 years or older) where the histological type is favorable when the tumor diameter is < or =1.0 cm and when microcalcification or spiculation is absent on mammography.     

Prognostic factors that predict pelvic lymph node metastasis from endometrial carcinoma

BACKGROUND: Recent reports indicate that certain pre- and intraoperatively determined risk factors are predictive of pelvic lymph node metastases from endometrial cancer, allowing selective pelvic lymph node dissection. The objective of this study was to evaluate the accuracy of pre-, pre-/intra- and postoperatively determined tumor characteristics. METHODS: The study is based on 100 patients treated from 1987-1991 with total abdominal hysterectomy and bilateral salpingo-oophorectomy. In all patients thorough pelvic lymphadenectomies were performed (no sampling). These patients were evaluated according to different macroscopic and histologic tumor characteristics retrospectively in a blind fashion (the lymph node status was later determined separately). Multivariate analysis was applied and the results were compared using receiver operator characteristic curves. In 15 of 100 patients, pelvic lymph node metastases could be histologically demonstrated. RESULTS: Multivariate analysis of 22 tumor characteristics identified the following as being independent in relation to pelvic lymph node metastases: preoperatively determined characteristics: serous papillary tumor type, invasion of myometrium, and histologic grade (Christopherson); pre-/intraoperatively: serous papillary type, histologic grade (Christopherson), and cervical involvement; and postoperatively: lymphangiosis carcinomatosa and hemangiosis carcinomatosa. Receiver operator characteristic curves show that for pelvic node metastases the postoperatively determined histologic findings are more predictive than all other factors that can be evaluated pre- and/or intraoperatively. CONCLUSION: Pre- and intraoperative tumor characteristics can determine the individual risk for pelvic lymph node involvement, but additional studies addressing the therapeutic value of pelvic lymphadenectomy would be necessary to define a probability threshold for lymphadenectomy in a decision analysis.     

The postpubertal change in the playful defense of male rats depends upon neonatal exposure to gonadal hormones

Only 19 cases of metastases at the cannula insertion site after laparoscopy for gynecological malignancy have been reported in the literature. One case has been diagnosed with cervical squamous cell carcinoma, whereas the others have been diagnosed with ovarian cancer and borderline ovarian tumor. We present a novel case of laparoscopy-site abdominal wall metastasis from endometrial cancer after laparoscopic-assisted vaginal hysterectomy (LAVH). The 56-year-old female patient exhibited metastases of an abdominal wall trocar site and a perineal site after undergoing LAVH and laparoscopic-assisted (LA) bilateral pelvic lymph node sampling as well as LA para-aortic lymph node sampling for treating endometrial carcinoma, surgical staging IIIC, G3. The interval between the surgical extirpation of endometrial carcinoma and diagnosis of the tumor recurrence was 6 months, suggesting that overmanipulation of the diseased organ during laparoscopic surgery may have resulted in tumor spillage, intraperitoneal dissemination, and wound contamination. Although this procedure has been proven beneficial to patients with benign disease or early-stage gynecologic malignancies, laparoscopic-assisted vaginal hysterectomy may not be efficacious to eradicate advanced gynecological malignancy.     

Outpatient pelvic lymph node dissection

PURPOSE: Staging pelvic lymph node dissection is an important part of the evaluation of most patients with prostatic carcinoma. While laparoscopic pelvic lymph node dissection provides an alternative to standard pelvic lymph node dissection, it has been associated with a significant learning curve, high major complication rate, frequent hospitalization and greater expense. We sought to modify the technique of pelvic lymph node dissection to allow its performance as an outpatient procedure. MATERIALS AND METHODS: Pelvic lymph node dissection was performed through bilateral 3 cm. incisions overlying the obturator fossa in 11 patients. RESULTS: Nodes sampled ranged from 5 to 26 per patient that differed insignificantly from those undergoing standard pelvic lymph node dissection. Four patients had lymph node metastases. Nine procedures were performed entirely on an outpatient basis. One complication (external vein injury) was repaired with a single suture after extending the incision to 6 cm. CONCLUSIONS: Outpatient pelvic lymph node dissection through small incisions provides an attractive alternative to standard or laparoscopic lymph node dissection. With further experience it may become the procedure of choice for staging prostatic carcinoma in patients with a high risk of pelvic lymph node metastases.     

Systematic sextant biopsies improve preoperative prediction of pelvic lymph node metastases in patients with clinically localized prostatic carcinoma

PURPOSE: An algorithm including the results of systematic sextant biopsies was statistically developed and evaluated to predict the probability of pelvic lymph node metastases in patients with clinically localized carcinoma of the prostate. MATERIALS AND METHODS: Clinical stage, serum prostate specific antigen concentration, Gleason score, number of positive biopsies, number of biopsies containing any Gleason grade 4 or 5 cancer and number of biopsies predominated by Gleason grade 4 or 5 cancer were recorded in 345 patients undergoing pelvic lymph node dissection and correlated with the incidence of lymph node metastases. Multivariate logistic regression, and classification and regression trees analyses were performed. RESULTS: In univariate analysis all variables had a statistically significant influence on lymph node status. Logistic regression showed that the amount and distribution of undifferentiated Gleason grade 4 and 5 cancer in the biopsies were the best predictors of lymphatic spread followed by serum prostate specific antigen. Classification and regression trees analysis classified 79.9% of patients who had 3 or fewer biopsies with Gleason grade 4 or 5 cancer and no biopsies predominated by undifferentiated cancer as a low risk group. In this group positive lymph nodes occurred in only 2.2% (95% confidence interval 0.8 to 4.7%). CONCLUSIONS: Including the results of systematic sextant biopsies substantially enhances the predictive accuracy of algorithms that define the probability of lymph node metastases in prostatic cancer. Patients thus defined as having no lymphatic spread could potentially be spared pelvic lymph node dissection before definitive local treatment.     

Review of US medical school finances, 1995-1996

We discussed the rational extent of the lymph node dissection for carcinoma of the lower third of the esophagus of T2 or T3 stage with abdominal lymph node metastasis. Lymph node metastasis developed in 89.5% of patients. Cervical lymph node metastasis was seen in 35.8%. In the cases with positive abdominal lymph node, 40.9% of the patients had cervical node metastasis. The most frequent site of the positive node in the neck is the area along the right recurrent laryngeal nerve. On the stand point of removal of metastatic lymph node, neck dissection should be required. Three-field dissection yielded better survival rate than two-field dissection but statistical significance was not obtained. When the patients have cervical lymph node metastasis, they have greater possibility of developing blood borne metastasis. However, this observation does not deny the validity of the three-field dissection. Because this dissection may help reducing nodal spread and nodal recurrence. We have to wait for accumulation of the patients to analyze the definite extent of node dissection for T2 or T3 stage of carcinoma of the lower third of the esophagus with positive abdominal lymph node.     

Value of peritoneal cytology after hysteroscopy in surgical stage I adenocarcinoma of the endometrium

Nineteen clinical stage I adenocarcinoma of the uterus with favourable histological prognosis factors (low grade, no myometrial extension, and no pelvic node involvement) were diagnosed using a pre-operative hysteroscopy. During the laparotomy, peritoneal cytology was performed systematically. The frequency of positive peritoneal washings was abnormally high (7 cases) with cytologic findings showing grouped cells in large clusters. However, these patients have not experienced peritoneal recurrences. The endoscopic procedures may have facilitated the transtubal malignant cell dissemination and are questionable in endometrial carcinoma.     

Lymph node metastasis in stage I ovarian carcinoma

One hundred and sixteen cases of stage I ovarian cancer from 6 hospitals in China were investigated for their lymph node metastasis from September, 1982 to April 1991. Of them, 70 had epithelial tumor, 36 malignant germ cell tumor, 8 gonadal stroma, and 2 undifferentiated tumor. Ovarian tumor confined to one ovary (stage Ia) in 89 patients, both ovaries involved (stage IIb) in 6, and documented stage Ic in 21. Systemic lymphadenectomy involving all pelvic groups of node together with aortic lymph node was accomplished in 82 patients. In the remaining 34 patients, pelvic lymph node dissection was performed. The incidence of lymphatic metastasis was 10.3% in this series. Serous cystadenocarcinoma was the most common lesion. All patients were followed up for at least half year. The mortality rate in patients with and without lymph node metastasis was 8.3% and 2.8% respectively. The clinical significance of retroperitoneal lymphadenectomy in early ovarian carcinoma was discussed.     

Value of peritoneal cytology after hysteroscopy in endometrial adenocarcinoma stage I

Nineteen clinical stage I adenocarcinoma of the uterus with favourable histological prognosis factors (low grade, no myometrial extension, and no pelvic node involvement) were diagnosed using a preoperative hysteroscopy. During the laparotomy, a peritoneal cytology was performed systematically. The frequency of positive peritoneal washings was abnormally high (7 cases) with cytologic findings showing grouped cells in large clusters. However, these patients have not experienced peritoneal recurrences. The endoscopic procedures may have facilitated the transtubal malignant cell dissemination and are questionable in front of endometrial carcinoma.

A series of 60 patients with squamous cell carcinoma of the larynx who underwent surgery of the primary tumor and elective bilateral neck dissection were reviewed to determine the importance of certain clinical and pathological features as risk factors for lymph node metastasis. Tumor location, extension to the vallecula and to the pyriform sinus, T stage, histological grade, palpable lymph nodes, laryngeal motility, and macroscopic aspects were studied. Logistic regression analysis demonstrated that T stage, tumor location, and palpable lymph nodes were the most important predictors of lymph node metastases.     

Lymphatogenous spread of renal cell carcinoma: an autopsy study

PURPOSE: We investigated the occurrence and extent of metastatic spread, especially regarding lymph nodes, of renal cell carcinoma. MATERIALS AND METHODS: From 1958 to 1982, 554 cases of renal cell carcinoma were diagnosed at autopsy. Clinical data and autopsy findings were reevaluated, and the occurrence of lymph node metastases was analyzed by histological examination of retroperitoneal, mediastinal, supraclavicular, axillary and inguinal lymph nodes. RESULTS: Distant metastases were revealed in 119 cases (21.5%), including 31 (5.6%) with single metastases. In 88 cases (16%) renal cancer was the cause of death. Lymphatogenous dissemination was detected in 80 cases of which 75 had additional, mostly multifocal metastatic spread. Consequently lymph node metastases restricted to the paracaval and/or para-aortic lymph nodes were noted in only 5 cases (0.9%). CONCLUSIONS: Of the 554 cases of clinically unrecognized renal cell carcinoma almost all with lymphatic spread had additional distant metastases. Therefore, the therapeutic effect of extensive retroperitoneal lymph node dissection in association with radical nephrectomy seems to be low. However, more limited lymph node dissection may be useful, mainly as a staging procedure.     

Axillary lymph node metastases of bronchogenic carcinoma

BACKGROUND: Metastasis of bronchogenic carcinoma to axillary lymph nodes is rare. The pathways and possible significance of axillary lymph node metastasis from bronchogenic carcinoma were investigated. METHODS: Seventeen patients with probable axillary lymph node metastases from bronchogenic carcinoma were identified by computed tomography. There were 15 nonsmall cell lung cancers and 2 small cell lung cancers. Axillary lymph node metastasis was proven by biopsy in six cases. Metastases were presumed because of an increase in the size of axillary lymph nodes compared with prior studies in six patients and enlarged axillary lymph nodes associated with biopsy-proven ipsilateral supraclavicular lymph node metastasis in five patients. RESULTS: Four of 10 right-sided lung cancers had ipsilateral and six had contralateral axillary lymph node metastases. Six of seven left-sided cancers had ipsilateral and one had contralateral axillary lymph node metastases. Patients with ipsilateral lymph node disease had chest wall involvement and/or supraclavicular and mediastinal lymph node metastases. All seven patients with contralateral axillary lymph node metastases had supraclavicular and/or mediastinal lymph node metastases. CONCLUSION: Bronchogenic carcinoma may involve ipsilateral axillary lymph nodes via either chest wall invasion or retrograde spread from supraclavicular lymph nodes. Contralateral axillary lymph node involvement requires involvement of contralateral mediastinal and supraclavicular lymph nodes with retrograde spread to the axillary lymph nodes.     

The significance of paracardiac lymph node enlargement in ovarian cancer

The computed tomography (CT) scans of 78 patients with stage II, stage III and relapsed stage I ovarian carcinoma were reviewed in order to identify the incidence of enlarged paracardiac lymph nodes in this disease, recognize their association, if any, with peritoneal metastases and establish whether they had any bearing on progression free interval and survival. Twenty-two patients (28%) were found to have enlarged paracardiac nodes, nine at initial presentation and a further 13 during the course of follow-up. The association between paracardiac node enlargement and peritoneal metastases was found to be highly significant. Thirty per cent of 27 patients with peritoneal metastases at presentation were found to have enlarged paracardiac nodes whereas of the 51 patients without peritoneal dissemination only 2% had enlarged paracardiac nodes (P < 0.001). In order to determine whether paracardiac nodal status had any independent prognostic value, multivariate analysis using Cox's regression was performed. When status at presentation was considered, the presence of enlarged paracardiac lymph nodes was found to be an independent predictor for survival. (Hazard ratio 3.70, 95% confidence interval (1.18-11.6), P < 0.04.) The hazard ratio for paracardiac nodal status with respect to progression free survival was not significant but in the expected direction. (Hazard ratio 1.85 (0.65-5.25).) When time-dependent covariate analysis was applied, paracardiac nodal status and peritoneal metastases status were found to be independent predictors for both progression free survival and overall survival. The presence of peritoneal metastases indicated a poorer prognosis than the presence of paracardiac lymph nodes, the hazards ratios for progression free survival were 12.9 and 2.58, respectively, and those for survival were 20.7 and 3.62, respectively. We have demonstrated that the presence of paracardiac lymph node enlargement is a significant adverse prognostic factor for both progression free interval and survival. The diagnosis of involved paracardiac lymph nodes is important as it can define patients having stage IV as opposed to stage III disease.     

The impact of histopathology on nodal metastases in minimal breast cancer

OBJECTIVE: To establish a model based on risk factor analysis to guide selective axillary lymph node dissection in patients with T1a and T1b breast cancers. DESIGN: Retrospective review to determine histopathologic features and patient demographic profiles that may influence the incidence of nodal metastases. SETTING: Primary care and referral centers in Rhode Island and Massachusetts. PATIENTS: Women with invasive breast cancers with nodal status reported to the statewide tumor registry, the Hospital Association of Rhode Island, and the tumor registry at Baystate Medical Center, Springfield, Mass, between January 1984 and December 1995. There were 12030 patients with breast cancer reported; 2185 (18%) of these had tumors 1 cm or less in diameter. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Axillary node metastases. RESULTS: The nodal status of 377 patients with T1a tumors and 1808 patients with T1b tumors was studied. Seventy-five percent had axillary dissections, and 16% were found to have nodal metastases. Thirty-one percent (29/93) of patients younger than 40 years had positive nodes compared with 15% (241/1546) of older patients (P = .001). The T1a tumors had fewer metastases than the T1b tumors did (11% vs 17%; P = .02). Nuclear grade was available in 49% of cases. Nuclear grades 2 and 3 were associated with nodal involvement twice as often as grade 1 tumors were (P = .002). Patients with no poor prognostic factors had a 7% or less chance of nodal involvement, while patients with all 3 poor prognostic indicators had a 33.5% chance of nodal involvement. CONCLUSIONS: Selective nodal dissection may be possible through risk factor analysis. Prospective registration of complete histopathologic information will allow more comprehensive analysis and may further enhance the selective treatment of patients with minimally invasive breast cancer.     

Prediction of occult neck metastases in laryngeal carcinoma: role of proliferating cell nuclear antigen, MIB-1, and E-cadherin immunohistochemical determination

The aim of this study is to investigate the predictive value of proliferative activity assessment and E-cadherin expression by means of immunohistochemistry in identifying patients with laryngeal squamous cell carcinoma at a high risk for occult node metastasis. Thirty consecutive patients treated for laryngeal carcinoma with false clinically negative nodes (occult metastases, pN+) between the years 1980 and 1990 were selected for this study. A group of 30 cases with negative cervical lymph nodes (pN-) having a similar anatomic site and tumor size distribution was used as control. In each case, several histological parameters, including grade, pattern of invasion, number of mitosis (x10 high-power field), tumor inflammatory infiltrate, and tumor sclerosis, were assessed. Proliferative activity was determined using immunohistochemical staining for proliferating cell nuclear antigen (PCNA) and MIB-1. Other putative prognostic factors investigated at the immunohistochemical level were the cell adhesion molecule E-cadherin and two oncoproteins, p53 and c-erbB-2. In pN+ cases, the expression of PCNA and MIB-1 was significantly higher than in the pN- group. Moreover, a significant loss of E-cadherin expression was observed in carcinomas with occult metastases. No differences in p53 and c-erbB-2 oncoproteins were found between pN+ and pN- cases. Among the other pathological parameters examined, only histological grade was significantly associated with the presence of occult metastases, but on multivariate analysis, this relationship was lost. We conclude that PCNA, MIB-1, and E-cadherin are independent predictors of occult nodal disease in laryngeal squamous cell carcinoma, and their immunohistochemical determination could be useful in identifying patients with clinically negative lymph nodes who are at considerable risk for occult metastases and who may benefit from elective neck dissection.     

Medical Information Bus usage for automated IV pump data acquisition: evaluation of usage patterns

SUMMARY: lymph node involvement in renal cell carcinoma is factor of very poor prognosis. In a series of 55 node-positive patients, 33 (60%) had simultaneous renal vein or vena cava invasion and 32 (58.2%) had metastases. Gross lymph node involvement was found in 39 patients (70.9%). Patients without venous invasion or metastasis may have a prolonged survival. In this group, those with microscopic nodal involvement can be cured, as the 10 and 15-year the actuarial survival rate is 54.5% Formal lymphadenectomy might have played a role in these results. Surgery can be performed when vein invasion is present without metastasis, but the prognosis is generally poor. Survival does not seem to be influenced by surgery when metastasis is present, regardless of the vein status.     

Prediction of axillary lymph node involvement of women with invasive breast carcinoma: a multivariate analysis

BACKGROUND: The increasing use of systemic therapy for women with lymph node negative breast carcinoma and earlier stage of disease at mammographic detection raises questions regarding the need for routine axillary lymph node dissection. Predictive modeling for lymph node involvement may be one way to reduce the need for axillary lymph node dissection and its morbidity. METHODS: A multivariate analysis of 12 factors predictive of axillary lymph node involvement was conducted in a population-based cohort of 4312 women with invasive breast carcinoma diagnosed between January 1, 1993 and December 31, 1996. RESULTS: Clinical palpability, lymphatic or vascular invasion, lesion size, margin status, histology, and patient age were independent predictors of axillary lymph node involvement. The model correctly identified lymph node status in 76.6% of cases. Model accuracy and fit were equally high when applied to randomly selected halves of the study subjects. Approximately 32.0% of the patients in the study sample (1363/4312) were identified as having an extremely high (91%; n = 1102) or low (10%; n = 261) risk of lymph node involvement. In a second analysis, a clinically useable, three-variable model identified a very low risk group of patients (n = 147) with a 4.8% risk of lymph node metastasis and a high risk group of patients (n = 1008) with a 74.2% risk of lymph node metastasis. Greater than 90% of subjects in the high risk group received adjuvant systemic therapy even if they were lymph node negative pathologically. CONCLUSIONS: A clinically useable, three-variable model employing tumor and lymph node palpability, size, and lymphatic or vascular invasion can identify women with invasive breast carcinoma in whom axillary lymph node dissection is very unlikely to alter recommendations regarding adjuvant systemic therapy.     

Structure-function studies on the inhibition of binding of alpha-thrombin to platelet GpIb alpha by the peptide D-Y-Y-P-E and the artifactual inhibitory activity of C-terminal E in this peptide

In papillary thyroid carcinoma lymphnode metastases at presentation do not seem to adversely affect survival, but do increase the risk of loco-regional tumor recurrence. The value of systematic versus selective lymphadenectomy is far less standardized, whereas the role of postoperative radioiodine in preventing either nodal recurrence or cancer death remains controversial. Clinical data of 36 N+ patients with papillary thyroid carcinoma who had undergone from 1990 to 1996 ipsilateral or bilateral neck dissection were retrospectively reviewed, to analyse the value of systematic lymphadenectomy. In our series of 50 extensive lymph node dissections (levels 2-6), the number of metastases in each specimen (mean value: 5) and the incidence of multiple level metastases (36%) were high. In 37.5% of the metastases at level 6 and in 11.1% at level 4, coexisting nodal involvement at level 2 was observed, without metastasization at intermediate levels. Multiple levels metastases and skip metastases were present in at least one third of the patients and could be excised only performing a complete dissection of the levels 2-6. Extra-capsular spread was found in 56% of the specimens. In 64.3% of these cases a functional neck dissection was performed. A modified radical or radical neck dissection was carried out in the other 35.7% of the cases. These patients received modified radical neck dissection (functional dissection with sacrifice of internal jugular vein) in 60% of the cases and radical neck dissection in the other 40%. In papillary thyroid carcinoma extensive lymphnode dissection at presentation has been stated to offer no advantage versus selective lymphadenectomy, causing increased morbidity. However, experienced surgeons report a low incidence (less than 5%) of accessory spinal nerve and cervical plexus permanent sequelae after functional neck dissection. In our opinion, patients with cervical lymph node metastases require a complete loco-regional neck dissection. Systematic lymphadenectomy, performed by lateral neck plus upper anterior mediastinal dissection, can yield a high disease-free survival. Moreover, this can limit the overall radio-iodine therapeutic dose and the risk of de-differentiation of recurrent tumor to the anaplastic type in patients with a long-term and near normal life-span.
