Comparison of Clinical Stage, Therapy Response, and Patient Outcome Between Squamous Cell Carcinoma and Adenocarcinoma of the Esophagus. ACTA ACUST UNITED AC 2005; 36:69-76. [PMID: 16648656 DOI: 10.1385/ijgc:36:2:69] [Citation(s) in RCA: 14] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/1999] [Revised: 11/30/1999] [Accepted: 11/30/1999] [Indexed: 11/11/2022]
Abstract
PURPOSE To analyze the differences in clinical stage, pathologic response to chemoradiotherapy, patterns of failure, and overall survival (OS) between patients with squamous cell carcinoma (SCC) and adenocarcinoma (ACA) of the esophagus. PATIENTS AND METHODS We stratified patients by two histologies, ACA and SCC, and statistically compared their clinical stage, post-therapy pathologic response, patterns of failure, and OS. RESULTS Of the 235 patients who underwent preoperative chemoradiotherapy, 42 (18%) had SCC and 193 (82%) had ACA. Among the ACA patients, a significantly larger proportion was male (93% vs 7%; p <0.001), whereas sex was distributed similarly among SCC patients (55% male vs 45% female; p = 0.5). A significantly larger percentage of SCC patients were classified as lower TN and overall stage than ACA patients (T2 = 41% vs 28%, p <0.0001; N0 = 69% vs 48%, p = 0.01; stage II = 76% vs 55%, p <0.001). A significantly greater portion of SCCs was categorized as pathologic N0 after treatment (71% vs 65%; p = 0.02). Among the pathCR patients in clinical stage II, there were significantly greater proportion of SCC patients (77% vs 63%; p <0.001) than ACA patients. Among the pathCR patients in clinical stage III patients, a significantly greater proportion were ACA patients (38% vs 23%; p <0.001) than SCC patients. The median and 5-yr OS was 53 +/- 11 mo and 39% for ACA patients and 35 +/- 14 mo and 37% for SCC (median OS, p = 0.3). Among pathCR patients, median OS of ACA patients (133 mo) was longer than that of SCC patients but nonsignificant (29 mo; p = 0.07); results were similar for non-pathCR patients. DFS results were similar in all subgroups. Among the whole cohort, incidence of local-regional recurrence and distant metastases did not vary significantly. The median time to distant metastases did not vary significantly for pathCR and non-pathCR patients. CONCLUSIONS We believe this is the first study that compares failure outcome of ACA and SCC patients with similar clinical stage after trimodality therapy. Our data suggest that significant differences in clinical stage and post-therapy pathologic stage exist between ACA and SCC. Frequent presence of malignant nodes in the resected specimens of ACA patients resulted in a shorter time-to-metastases suggesting that ACA patients need better systemic control.

Abstract
BACKGROUND The aim of this study was to compare the clinical features and proliferating cell nuclear antigen (PCNA), p53, Bcl-X, and Bax expression in primary oral basaloid squamous cell carcinoma (BSCC) and poorly differentiated squamous cell carcinoma (PDSCC) matched by stage and site and to assess the possible prognostic significance of these variables. METHODS Seventeen cases of oral BSCC were compared with 27 PDSCCs matched by stage and tumor site. In addition, PCNA, p53, Bax, and Bcl-X expression in both carcinomas were evaluated in relation to their clinicopathologic features and prognostic values using the Kaplan-Meier method and Cox regression models. RESULTS No statistically significant differences were found between the groups (BSCC and PDSCC) in regard to clinical features and immunohistochemical reactivity for antibodies PCNA, p53, and Bcl-X. In comparison with PDSCC, the BSCC group exhibited a higher Bax score (p = .031). The 5-year and 10-year overall survival, cancer-specific survival, and disease-free survival rates demonstrated no significant differences between the BSCC and PDSCC groups, and the PCNA, p53, Bax, and Bcl-X also showed no prognostic value. CONCLUSIONS These results suggest that the clinical and biologic course of BSCC is similar to PDSCC in the oral cavity when clinical stage and site are matched.

Abstract
OBJECTIVE The purpose of the present study was to evaluate the palliative effect of selective intra-arterial chemotherapy in progressive unresectable head and neck cancer previously treated with radiochemotherapy. PATIENTS AND METHODS 8 patients with advanced residual or recurrent squamous cell carcinoma of the head and neck were evaluated. These patients were included in the present study particularly because of progredient pain and recurrent bleedings due to tumor progression. In addition 6/8 patients suffered from unpleasant tumor-related smell. All patients received simultaneous infusions of cisplatin (150 mg/m2) intra-arterially to the tumor and sodium thiosulfate intravenously (9 g/m2) for systemic neutralization of cisplatin. The patients were treated by at most 4 cycles of selective intra-arterial chemotherapy via femoral approach. RESULTS Tumor-associated pain, occurrence of tumor bleeding and tumor-related smell were reduced after at least 2 cycles of intra-arterial chemotherapy in all patients. Clinical and radiological assessment of the primary tumor site revealed a partial response in 4 patients while 4 patients were classified as nonresponders. Intra-arterial cisplatin treatment was well tolerated. CONCLUSION Selective intra-arterial cisplatin therapy can be delivered safely for palliation of tumor-related symptoms of incurable head and neck cancer.

Abstract
BACKGROUND Routine follow-up offered to patients with laryngeal carcinoma in The Netherlands consisted of 22 routine visits over a time period of 10 years after treatment. The primary aims of the follow-up were to detect cancer recurrence in asymptomatic patients and to achieve better survival outcome by reducing cancer-specific mortality rates. METHODS A longitudinal cohort study was performed to evaluate the effect of this follow-up schedule. Between January 1990 and January 1995, the authors studied all patients with primary laryngeal squamous cell carcinoma who were treated with intention to cure. For patients who developed cancer recurrence, all routine and extra visits were documented. Reported symptoms and physical evidence of tumor were mapped. RESULTS The patients complied with the follow-up protocol closely. In only 2% of all routine visits an asymptomatic cancer recurrence was found. There was no difference in survival and tumor mortality rates for patients with and without symptoms, despite the difference in whether the therapy applied had the intention to cure. It seemed that patients who developed tumor recurrence after therapy for laryngeal carcinoma received no benefit from screening for cancer recurrence detection. The lack of benefit for cancer detection screening among asymptomatic patients might be explained by unfavorable tumor biology parameters. CONCLUSIONS The routine follow-up program after treatment for laryngeal carcinoma did not lead to survival benefit for asymptomatic patients with tumor recurrence.

Abstract
When induction chemotherapy is used in locally advanced squamous cell cancer of the head and neck (SCCHN), patients often receive cisplatin-5-fluorouracil (PF) followed by radical loco-regional therapy. Phase II studies of docetaxel-cisplatin-5-fluorouracil (TPF) induction therapy, with or without leucovorin (L), have achieved high survival rates versus those reported in phase III PF trials. However, the distribution of prognostic factors may vary between phase II and phase III study populations, making the extrapolation of phase II TPF/L results to phase III PF populations difficult. This study used a patient selection standardization method and Cox model to adjust for potential selection bias. Thus, the survival benefit from adding docetaxel into PF induction regimens in SCCHN could be more accurately assessed. The TPF/L dataset comprised 195 patients from six phase II trials. The PF dataset of 585 patients was derived from five large randomized trials included in the Meta-Analysis of Chemotherapy in Head and Neck Cancer (MACH-NC) database. TPF/L and PF datasets differed significantly concerning the distribution of several prognostic factors. Adjusting for these differences, the relative risk of death in the PF versus TPF/L datasets was 1.85 (95% confidence interval 1.37-2.49), corresponding to a 20% 2-year survival benefit (p < 0.0001). Sensitivity analyses confirmed that this improved 2-year survival rate of TPF/L over PF was robust, irrespective of the distribution of studied prognostic factors between treatment datasets. We conclude that this improved survival might be due either to docetaxel's pharmacologic effect or to uncontrolled prognostic factors.

Abstract
PURPOSE To determine the safety profile and activity of the combination of docetaxel, cisplatin and 5-fluorouracil (5-FU) in chemotherapy-naive patients with squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS Patients with locally advanced unresectable SCCHN were treated with docetaxel and cisplatin both as a 1-h infusion on day 1 followed by a continuous infusion of 5-FU for 5 days. Cycles were planned every 3 weeks up to four cycles, whereafter the patients were treated with locoregional radiotherapy. Two dose levels were studied. Doses in level I were 75 mg/m(2) of docetaxel, 75 mg/m(2) of cisplatin and 750 mg/m(2)/day of 5-FU; in level II the cisplatin dose was escalated to 100 mg/m(2). Following chemotherapy, all patients were to receive curative radiotherapy according to the standards in the different institutions. RESULTS Twenty-five patients were treated at dose level I with 86 cycles (median four; range one to four), and 23 at dose level II with 84 cycles (median four; range two to four). The median relative dose intensity was 0.99 (range 0.86-1.04) at level I and 0.94 (range 0.79-1.02) at level II. The response rate in the intention-to-treat population was 64% [95% confidence interval (CI) 42.5% to 82%] in level I and 78.3% (95% CI 56.3% to 92.5%) in level II; all were partial responses. The maximum tolerated dose was reached at level II with renal toxicity, nausea, stomatitis and thrombocytopenia as principal dose-limiting toxicities. The median survival of the 48 patients was 18.5 months. The survival at 12, 18, 24 and 30 months was 69, 54, 41 and 31%, respectively. CONCLUSIONS The combination of docetaxel, cisplatin and 5-FU associated with prophylactic ciprofloxacin is feasible and active in patients with SCCHN. Dose level I is recommended for phase III testing.

Abstract
BACKGROUND Liver metastases from head and neck cancer are rare (4.4%) and associated with a poor prognosis (median survival 4 months). The objective of the present study was to evaluate the radiological and biological features of liver metastases from head and neck (H and N) squamous cell carcinomas in 24 patients among 550 recurrent H and N cancer patients in our data bank. RESULTS At first presentation of liver nodules, liver enzyme levels (LEL) were found to be abnormal in 46% of patients (n = 11). Ultrasound features included miscellaneous presentations such as hypoechogenic (n = 21), hyperechogenic hemangioma-like lesions (n = 2), owl's eye (n = 2) or cyst-like liver nodules (n = 3). Hepatomegaly was present in 48% of the cases without any sign of portal hypertension and without any ascites. 1 month before death, all patients presented with abnormal LEL. Liver imaging showed an increase of 1.8x in size and of 2x in number of the tumor nodules. Hepatomegaly was present in 54%. Little ascites appeared in 2 cases, with no evidence of portal hypertension or liver insufficiency. Median disease-free interval and overall survival from recurrence were 10.8 and 4 months, respectively. CONCLUSION Ultrasound is convenient, cheap, without any side effect, and can provide additional information about liver metastases in H and N cancer patients. In patients with a history of H and N carcinoma ultrasound should be used to screen for isolated hepatic nodules even in the presence of normal liver function and if LDH elevation should be the only biological sign of alert.

Abstract
OBJECTIVE To study the prognostic factors affecting the survival rate after extended radical esophagectomy with three-field lymph node dissection for squamous cell carcinoma and the effect of postoperative chemotherapy. METHODS Out of 126 patients with original squamous cell carcinoma of esophagus who accepted extended radical esophagectomy with three-field lymph node dissection from 1987 - 1992 in a hospital, 97 of them were included in this study. Data on the clinical/pathological characters and post surgery survival records of the subjects' were collected. Survival analysis methods included Kaplan-Meier, Log-rank test and Cox multivariable model and the effects of postoperative chemotherapy were analyzed for patients in early and late stages. RESULTS There was no significant difference in clinical and pathological character between those patients only undergone surgery and patients accepting postoperative chemotherapy. The size of tumor, grade of differentiation of the tumor cells, infiltration deepness, with or without lymph node metastasis, expression of nm23 and EGFR and treatment after surgery etc. were correlated with the survival rate. For patients in early tumor stage, postoperative chemotherapy with cisplatin and 5-FU after surgery seemed to be a risk factor. For patients in late stage, postoperative chemotherapy with cisplatin and 5-FU after surgery did not seem to improve survival rate. CONCLUSION It is imperative to study on the effect of adjuvant postoperative chemotherapy to patients, especially those at early stage with squamous cell carcinoma of esophagus. Doctors must be scrupulous when making decisions.

Abstract
BACKGROUND In order to improve our cisplatin-5-fluorouracil (5-FU)-based alternating chemo-radiotherapy regimen, in 1996 we started an investigational program to explore a modified alternating regimen including gemcitabine given both with radiosensitizing and cytotoxic intent. MATERIALS AND METHODS Based on our previous feasibility trial, we conducted a second study testing the feasibility and activity of the following schedule: gemcitabine 800 mg/m(2) on day 1 and cisplatin 20 mg/m(2) on days 2-5 (weeks 1, 4, 7 and 10) alternated with three courses of radiotherapy (RT) (weeks 2-3, 5-6 and 8-9) with conventional fractionation up to 60 Gy. Gemcitabine 300 mg/m(2) was also administered on the Monday of each week of RT. RESULTS Forty-seven patients with stage IV (41 patients) unresectable squamous cell carcinoma of the head and neck (SCC-HN) or who had relapsed after surgery (6 patients) were enrolled. None had previously received chemotherapy or radiotherapy. Eight patients (18%) did not complete the treatment. Main grade 3-4 toxicities were as follows: neutropenia (44%); neutropenia with fever (12%); thrombocytopenia (37%); anemia (30% grade 3). One patient died in therapy due to sepsis. Most patients needed hospitalization and tube-feeding or parenteral nutrition. However, 44% of patients had a weight loss >10%. Thirty-four patients had a complete response (72%). Three partial responders were rendered disease-free by surgery (final complete response rate, 79%). At a median follow-up of 38 months actuarial 3-year overall survival, progression-free survival and loco-regional control are 43%, 39% and 64%, respectively. Data of locoregional control favorably compare with those from our database of patients treated with alternating cisplatin-fluorouracil and radiation within controlled clinical trials (64% versus 40%). CONCLUSIONS The inclusion of gemcitabine into an alternating regimen seems to improve the results achievable with the original alternating program in stage IV patients. However, due to the high acute toxicity correlated, this intensive regimen should be managed by institutions well trained in multidisciplinary treatments.

Abstract
Regression rate of CIN 1 (LSIL) can reach 85%. The purpose of this study was to investigate retrospectively pathology specimens in CIN 1 cases who delayed treatment > 2 years despite the persistence of the lesion. One hundred and fifteen women diagnosed with CIN 1 were separated in two groups as follows: A) 92 women who underwent ablative treatment within three months after the completion of two years; B) 23 women who delayed ablative treatment for a mean interval of > 1 year after the completion of two years. Exclusion criteria were normal cytology and colposcopy results within the completion of two years. The chi-square, t-test and Kaplan-Meier method were used for analysis. Persistence of LSIL lesions was observed in 84% of the first group and persistence or regression of the lesion in 78% of the second one. The study suggests the possibility of prolongation of the observation period after LSIL diagnosis. Prospective studies with close follow-up are needed for final conclusions.

Abstract
BACKGROUND Comorbidity has been shown to be a determinant in treatment selection and survival in various cancers. We have previously shown that the Adult Comorbidity Evaluation-27 index is applicable in a United Kingdom setting, and the process of comorbidity grading by retrospective notes evaluation is an accurate and reliable process. METHODS The impact of comorbidity and other factors on survival was examined retrospectively in a cohort of 180 patients with laryngeal squamous cell cancer. RESULTS This study shows for the first time that the higher comorbidity burden seen in supraglottic cancers in contrast to glottic tumors might account for the poorer prognosis. This study also externally validates the composite comorbidity-TNM staging system described by Piccirillo and shows the composite system to be a better predictor of outcome than TNM staging system alone. CONCLUSIONS Moderate and severe comorbidity have a greater and statistically significant impact on survival than the TNM staging system.

Abstract
A Phase II trial in 42 patients with squamous cell cancer of the head and neck (H and NSCC) was performed using a combination immunotherapy with 10-20 days of perilymphatic injections of a natural cytokine mixture (NCM: IRX-2; 200 units IL-2 equivalence) preceded by low dose cyclophosphamide (CY; 300 mg/m(2)) and followed by daily oral indomethacin (25 mg t.i.d.) and zinc (65 mg in a multivitamin preparation). Thirty-nine patients underwent subsequent surgical resection and 22 stage IV patients received additional radiotherapy. Forty-two percent were adjudged to have complete and partial clinical responses (>50% tumor reduction); an additional five patients had minor responses for a total of 58%. Comparison of post-treatment biopsies or surgical specimens showed 90% of patients had reduction in tumor area from 79% to 48% (over half of which was fragmented) and increased area of leukocyte infiltration from 9% to 32% (79% of which was lymphoid). The treatment with IRX-2 was not associated with significant side effects and 24 of patients showed improvement in eating, breathing or phonation or reduced pain and bleeding. Fifteen patients with lymphocytopenia (lymphocyte counts [LC] less than or equal to 1500 mm(3)) showed significant increases in LC, CD3+, CD4+ and CD8+ T lymphocytes of 401, 147, 95 and 100/mm(3), respectively. Analysis of outcome of 32 on protocol patients after 36 months versus 32 concurrent institutional H and NSCC controls showed delayed recurrences and significant increases in mean survival time (MST) and survival (p's<0.02). The data document immunotherapy induced regression of H and NSCC with delayed recurrence and improved mean survival time.

Abstract
Chemoradiotherapy (CRT) is now widely accepted as the primary treatment modality for squamous cell cancer of the anus. While randomised trials have clearly shown CRT to be more effective than radiotherapy alone, there remains uncertainty over the optimal integration of chemotherapy and radiation. We describe a series of 50 patients treated by a site specialist gastrointestinal nonsurgical oncologist with CRT at a single UK centre. Chemotherapy comprised mitomycin C (MMC) (day 1) and 5-fluorouracil (5-FU) (days 1-4, and 29-32), concurrent with 50 Gy in 25 fractions radiation, using a two-phase shrinking field technique. A radiation boost was not planned. At a median follow-up of 48 months, 11 (22%) of the patients have failed locally, of which three have been surgically salvaged. Nine (18%) have died of anal cancer. These results are comparable with those from large randomised studies, and suggest that a two-phase shrinking field radiotherapy technique with no boost, concurrent with MMC/5-FU chemotherapy, is an effective regimen for this disease. The CRT regimen described here provides the basis for the 'control arm' of the current UK-randomised CRT trial in anal cancer (ACT2).

Abstract
PURPOSE To determine the influence of waiting time for radiotherapy on local control and survival in a cohort of patients with head and neck carcinoma of different locations and stages treated with radiotherapy. MATERIAL AND METHODS Retrospective study of 797 patients with squamous cell carcinoma located in the oral cavity, pharynx or larynx, treated with radiotherapy, and with a minimum follow-up of 3 years. Local recurrence and survival were analyzed in function of the waiting time, defined as the interval between date of histologic diagnosis and date of radiotherapy. A univariate and multivariate analysis was carried out. RESULTS Median waiting time to radiotherapy was 44 days (25 and 75% quartiles: 33 and 60 days). There were significant differences in the waiting time period in relation to the primary location and the local extension of the tumor. Both univariate and multivariate analysis showed that waiting time had no significant impact either on local control or survival. CONCLUSION Within the range of the waiting time observed in our study, delay in the initiation of radiotherapy did not affect local control or survival in patients with head and neck carcinoma.

Abstract
The treatment results of new hyperfractionated, accelerated, split course irradiation schedule were presented. The material consisted of 27 (22 men, 5 women) advanced (T2N2C-3, T3-4 N2-3), inoperable head and neck (11--oropharynx, 9--larynx, 6--tongue, 1--hypopharynx) squamous cell cancer patients. Patients were in good performance status (Zubrod < or = 2). The age varied from 44 to 70 years (mean 56). All patients were irradiated using 6 MV photon beams, 1.6 Gy per fraction delivered twice a day with 6 hours of gap to the total dose of 64 Gy in the overall treatment time of 28 days (with 8 days long gap in the middle of treatment) to avoid accelerated clonogens repopulation. No one patient had a gap caused by treatment adverse effects. The highest mucosal acute reaction evaluated using Dische scale appeared in 3-4 week of treatment and varied from 6 to 25 points (mean 16 points). The analysis shown 34% total survival and 41% survival excluding death caused by a distant dissemination, in the period of 50 months. No correlation between T and N stage, tumour and nodes diameters and degree of regression and survival probability was found. The obtained results allow to conclude that CHA-CHA schedule is safe and acceptable by patients irradiation modality giving promising treatment results but the final confirmation of its value should be proven in a next, randomised phase of trial.

Abstract
PURPOSE The Head and Neck Intergroup conducted a phase III randomized trial to test the benefit of adding chemotherapy to radiation in patients with unresectable squamous cell head and neck cancer. PATIENTS AND METHODS Eligible patients were randomly assigned between arm A (the control), single daily fractionated radiation (70 Gy at 2 Gy/d); arm B, identical radiation therapy with concurrent bolus cisplatin, given on days 1, 22, and 43; and arm C, a split course of single daily fractionated radiation and three cycles of concurrent infusional fluorouracil and bolus cisplatin chemotherapy, 30 Gy given with the first cycle and 30 to 40 Gy given with the third cycle. Surgical resection was encouraged if possible after the second chemotherapy cycle on arm C and, if necessary, as salvage therapy on all three treatment arms. Survival data were compared between each experimental arm and the control arm using a one-sided log-rank test. RESULTS Between 1992 and 1999, 295 patients were entered on this trial. This did not meet the accrual goal of 362 patients and resulted in premature study closure. Grade 3 or worse toxicity occurred in 52% of patients enrolled in arm A, compared with 89% enrolled in arm B (P <.0001) and 77% enrolled in arm C (P <.001). With a median follow-up of 41 months, the 3-year projected overall survival for patients enrolled in arm A is 23%, compared with 37% for arm B (P =.014) and 27% for arm C (P = not significant). CONCLUSION The addition of concurrent high-dose, single-agent cisplatin to conventional single daily fractionated radiation significantly improves survival, although it also increases toxicity. The loss of efficacy resulting from split-course radiation was not offset by either multiagent chemotherapy or the possibility of midcourse surgery.

Abstract
OBJECTIVE The expression of uPA and PAI-1 as parameters of tumour-associated proteolysis has been implicated in the process of tumour cell invasion and the metastatic process. However, there is limited information on the impact of these parameters in cervical carcinoma. METHODS Quantitative levels for uPA (n = 114) and PAI-1 (n = 103) were researched in operatively treated, surgically staged squamous cell cancer of the uterine cervix, using an ELISA-technique. Results were assessed regarding their impact in predicting pelvic lymph nodes metastases, tumour recurrence rate and recurrence free survival (RFS) using uni- and multivariate analysis. RESULTS Median levels of both parameters were significantly higher in tumour tissue than in normal cervical tissue (p < 0.001). Detection of uPA gave no useful prognostic information. PAI-1 concentration showed a positive correlation with advanced tumour stage (p = 0.008), but no significant correlation with nodal status (pN0: 2.6 vs. pN1: 4.0 ng/mg protein; p = 0.092). Using a cut-off level of 2.4 ng/mg protein, patients with elevated PAI-1 levels demonstrated reduced RFS (45.9 versus 52.9 months; p = 0.1). Multivariate analysis, including nodal status, tumour stage, lymphovascular space involvement and grading failed to demonstrate any prognostic impact of uPA and PAI-1. CONCLUSIONS The results indicate, that PAI-1 expression is of some prognostic impact in cervical cancer, indicating an association of elevated PAI levels with local tumour progression and reduced recurrence-free survival.

Abstract
OBJECTIVE To review our experience in surgical treatment of 326 cases of thoracic esophageal carcinoma. METHODS The clinical data of 326 patients with thoracic esophageal carcinoma from January 1990 to January 2001 were analyzed retrospectively. Among the 326 patients, the lesions of 32 patients were identified in the upper thoracic segment of the esophagus, and were found in the middle segment in 213 cases with the left 81 cases having lesions in the lower segment. Left cervical esophagogastrostomy was performed through triple incision (left cervical, right thoracic and abdominal) in 79 cases. Esophagocolostomy through triple incision was performed in 5 cases. Another 156 patients received left cervical esophagogastrostomy through two incisions (left cervical and left thoracic). Supra-aorticarch esophagogastrostomy through left posterola- teral thoracotomy was performed in 53 cases, and sub-arch esophagogastrostomy through left posterolateral thoracotomy in 33 cases. RESULTS The post-operative mortality was 1.23% (4/326), with a five-year survival rate of 35.3%. CONCLUSION Subtotal esophagectomy combined with thorough lymph node dissection can be the first choice for thoracic esophageal carcinoma to improve the postoperative survival rate and the quality-of life-of the patients.

Abstract
Squamous-cell cancer (SCC) isolated to the anterior nose is uncommon. Numerous industrial and environmental contaminants have been implicated as causative factors in nasal carcinoma. The association between nasal cancer and smoking was recognized in the 1980s, but results have not been consistent and no possible mechanisms have been suggested. The case histories of 11 patients with SCC limited to the anterior nasal cavity were reviewed. The authors found no relationship with exposures to chemicals previously implicated in nasal cancer. Nine patients with SCC were exposed to cigarette smoke (mean = 103 pack-years). Cigarette smoke may induce cancer directly, thus affecting the mucosa, or by inducing genetic alterations. The authors favor the former mechanism.

Abstract
OBJECTIVE To determine the prevalence of occult cervical nodal metastases in patients with squamous cell cancer and adenocarcinoma of the esophagus, and to determine the impact of esophagectomy with three-field lymph node dissection on survival and recurrence rates. SUMMARY BACKGROUND DATA Although esophagectomy with three-field lymph node dissection is commonly practiced in Japan, its role in the surgical management of esophageal cancer in the United States, especially in patients with esophageal adenocarcinoma, is essentially unknown. METHODS This is a prospective observational study of esophagectomy with three-field lymphadenectomy. Eighty patients underwent resection between August 1994 and April 2001. Clinicopathological information and follow-up data were collected on all patients until death or June 2001. RESULTS Hospital mortality and morbidity rates were 5% and 46%, respectively. Metastases to the recurrent laryngeal and/or deep cervical nodes occurred in 36% of patients irrespective of cell type (adenocarcinoma 37%, squamous 34%) or location within the esophagus (lower third 32%, middle third 60%). Overall 5-year and disease-free survival rates were 51% and 46%, respectively. Sixty-nine percent presented with nodal metastases. The 5-year survival rate for node-negative patients was 88%; that for those with nodal metastases was 33%. The 5-year survival rate in patients with positive cervical nodes was 25% (squamous 40%, adenocarcinoma 15%). CONCLUSIONS Esophagectomy with three-field lymph node dissection can be performed with a low mortality and reasonable morbidity. Unsuspected metastases to the recurrent laryngeal and/or cervical nodes are present in 36% of patients regardless of cell type or location within the esophagus. Thirty percent of patients were upstaged, mainly from stage III to stage IV. An overall 5-year survival rate of 51% suggests a true survival benefit beyond that achieved solely on the basis of stage migration.

Abstract
The activity of docetaxel (Taxotere) as a single agent (overall response rates, 24%-45%) in the treatment of patients with recurrent squamous cell cancer of the head and neck has resulted in the investigation of docetaxel-based doublet and triplet combinations in both the recurrent and neoadjuvant settings. When combined with cisplatin, with or without fluorouracil (5-FU), in the treatment of recurrent disease, response rates of 33% to 44% have been observed for docetaxel, with median survival ranging from 9.6 to 11 months. In the neoadjuvant setting, response rates have been typically greater than 90%, with promising disease-free and overall survival results. Randomized trials are now under way to assess the value of docetaxel-based therapy relative to that of the standard cisplatin/5-FU combination in both the neoadjuvant and recurrent settings. Preclinical data indicate that docetaxel is a potent radiosensitizer and its initial evaluation with concurrent radiation in patients with locally advanced unresectable squamous cell cancer of the head and neck suggests feasibility. Phase II evaluation of this approach is in progress.

Abstract
BACKGROUND We wanted to investigate the clinical usefulness of determining the pretreatment levels of multiple serum tumor markers in predicting lymph node status and the prognosis for patients with cervical carcinoma. METHODS The preoperative serum levels of squamous cell carcinoma antigen (SCC), cancer antigens CA125 and CA19-9 were assayed simultaneously in 103 patients with stages IB to IIB cervical SCC undergoing radical hysterectomy. The cut-off values of SCC, CA125, and CA19-9 in this study were 1.5 ng/ml, 35 U/ml, and 37 U/ml, respectively. The relation between preoperative tumor marker levels and histopathologic prognostic factors including lymph node metastasis and patient survival was studied. RESULTS Preoperative serum SCC, CA125, and CA19-9 levels were significantly related to the FIGO stage. In addition, serum SCC and CA125 levels were significantly related to tumor diameter, depth of cervical stromal invasion, lymph-vascular space invasion, and lymph node metastasis. We subsequently created a double-tumor-marker (DTM) index, which incorporated the number of positive markers of SCC and CA125. The DTM index was strongly related to the number of positive pelvic lymph nodes (p = 0.0002) and to the site of positive nodes (none vs. pelvic only vs. common iliac/paraaortic) (p = 0.0005). Probability of lymph node metastasis according to the DTM index = 0, 1, and 2 was 6/48 (12.5%), 14/45 (31.1%), and 8/10 (80.0%), respectively. The rate of common iliac/paraaortic node metastasis according to the DTM index = 0, 1, and 2 was 1/48 (2.1%), 2/45 (4.4%), and 3/10 (30.0%), respectively. By logistic regression analysis, it was shown that the DTM index and tumor diameter were independently related to lymph node metastasis. Using multivariate Cox regression analysis including singly determined serum SCC and CA125 levels, clinical stage (IB/IIA vs. IIB), tumor diameter (<or= 2 vs. 2-4 vs. > 4 cm), parametrial invasion, lymph node metastasis, and the DTM index, the DTM index was found to be the most important prognostic factor (p = 0.0005). However, when the sites of positive nodes were included in the multivariate analysis, only the sites of positive nodes (p = 0.0008) and parametrial invasion (p = 0.041) showed independent prognostic significance. CONCLUSION Combination assay of pretreatment serum SCC and CA125 levels seems to be useful in estimating lymph node status and the prognosis for patients with cervical SCC in a preoperative setting.

Abstract
OBJECTIVE To study the expression of human epidermal growth factor receptor (HER) family in lung cancer. METHODS Paraffin-embedded tissues from 70 cases of lung cancer (43 cases of squamous cell cancer and 27 cases of adenocarcinoma) and 20 cases of non-cancerous lung diseases were stained for the expression of HERs by means of immunohistochemistry. RESULTS All HERs were weakly expressed in non-cancerous lung tissues; over-expression of HER(1), HER(2), HER(4), HER(1 + 2), HER(1 + 4) and HER(2 + 4) and HER(1 + 2 + 4) was found in lung cancer and correlated with lymph node metastasis, TNM staging and post-operation survival. CONCLUSIONS erbB(1), erbB(2) and erbB(4) are the genes regulating the growth of lung cancer at advanced stages. Targeting the HER(1), HER(2) and HER(4) over-expression might be a new approach to the treatment of lung cancer at advanced stages.

Abstract
BACKGROUND To assess the effect of clinicopathologic factors on local tumor control and survival in patients with mandibular alveolar carcinoma. METHODS Fifty patients with mandibular alveolar carcinoma treated surgically were included in this study. There were 3 patients with T1, 25 with T2, 5 with T3, and 17 with T4 disease. Clinical evidence of bone invasion was noted in 47 patients. A hemi- or segmental mandibulectomy was performed on 37 patients, whereas 10 patients had a marginal mandibulectomy. The impact of clinicopathologic variables on local tumor control and patient survival was assessed by univariate analysis. Variables included T and N stage, dental extraction, treatment modality, tumor differentiation, nodal status, surgical margin, and bone invasion. RESULTS Eleven patients (22%) develop recurrent disease, including 8 local recurrences, 1 neck, and 2 distant metastases. Overall, the 5-year actuarial rates of local control and disease-specific survival were 85 and 73%, respectively. Most local recurrences after surgical treatment were caused by inadequate resection margins. When resection margins were negative, the survival and local control rate were significantly better than when there were positive resection margins (survival, 91 vs. 11%; local control, 100 vs. 49%; p < 0.01). Neither T and N stages, clinical stage, tumor differentiation, dental extraction, bone invasion, extent of bone resection, nor treatment modality influenced outcome. CONCLUSIONS The status of surgical margins was of major importance for the outcome of patients with gingival carcinoma of the mandible.
