Abstract
Squamous cell carcinoma of the hypopharynx remains a highly lethal disease. This article documents our experience with 132 patients undergoing surgical management of squamous cell carcinoma of the hypopharynx, of whom 80% received postoperative radiation therapy. Local-regional control was obtained in 61% of the patients. Five-year overall and disease-free survival rates were 30% and 41%, respectively. Prognosis was better in patients with limited disease: local disease permitting larynx-sparing surgery, N0/N1 clinical neck, and stage I/II/III disease. Cancer of the hypopharynx remains an aggressive entity associated with poor prognosis. Novel strategies stressing improved local-regional control with prevention of distant metastasis are warranted.

Abstract
OBJECTIVE To assess case-mix characteristics, treatment patterns, and outcomes for laryngeal cancer using the largest series of patients to date. DESIGN Analyses performed on retrospectively collected survey data submitted by hospitals for diagnostic periods 1980 through 1985 and 1990 through 1992 (with a 9-year follow-up for the long-term group). SETTING Broad spectrum of US hospitals (N = 769). PATIENTS Consecutively accrued series of patients with laryngeal cancer (N = 16,936), with only squamous cell carcinomas (N = 16,213) analyzed. INTERVENTIONS Surgery, radiation therapy, and chemotherapy. MAIN OUTCOME MEASURES Descriptive analyses of case-mix, diagnostic, and treatment characteristics plus recurrence and 5-year, disease-specific survival outcomes. RESULTS There was a slight increase across these years in stage IV disease and in radiation therapy (with or without surgery and/or chemotherapy). Overall diversity of management of this disease (by site and stage) was apparent. Five-year survival rates indicated a large difference between modified groupings of the T and N classifications, separating stages III and IV cases into localized disease (87.5% for T1-T2; 76.0% for T3-T4 cases) and regional metastasis (46.2%). CONCLUSIONS Regardless of improvements in entering data in hospital records (most commendably, staging), more rigorous standards are needed. Also, the small increase in advanced-stage patients indicates that efforts toward early detection have not been successful. The rise in radiation therapy perhaps reflected an increased use of nonsurgical treatment for early-stage patients and organ-sparing radiochemotherapy protocols for advanced-stage patients. Regrouping stages III and IV cases into localized disease vs regional metastasis appears to predict survival better. Ongoing refinements of the American Joint Committee on Cancer staging scheme will hopefully improve this cancer's classification.

Abstract
The radial forearm free flap was selected as a donor site in only 17 (11 percent) of 155 consecutive free flap mandible reconstructions performed over a 9-year period. It was used either as an osteocutaneous flap (58 percent), as a soft-tissue flap alone for coverage of a reconstruction plate (18 percent), to supplement another free flap (12 percent), or to salvage a previous reconstruction (12 percent). The most common underlying disease was epidermoid carcinoma (82 percent), the average patient age was 55 years, and the average length of follow-up was 13.5 months. Although there was one patient death, there were no anastomotic failures. Postoperatively, two patients experienced fracture at the donor site (12 percent), and three patients (18 percent) had hardware related problems such as exposure, infection, or both. Although early studies advocated using the osteocutaneous radial forearm flap as a preferred method in mandible reconstruction, superior donor site options such as the fibula have now relegated it to a minor role. The best remaining indication for its use today is for a limited posterior bone defect associated with a large adjacent mucosal loss. Osseointegrated implant capability is not important in this setting, and the short bone length needed for this application minimizes the potential for fracture at the donor site, a serious complication. Otherwise, the osteocutaneous radial forearm flap is not recommended for the majority of segmental mandibular defects. The radial forearm flap without bone continues to have an important supportive role in mandibular reconstruction. It is an excellent choice in this regard when used to cover a reconstruction plate, as a second free flap when soft-tissue requirements are exceptionally large, or for salvage of a previous mandible reconstruction.

Abstract
BACKGROUND Some patients undergoing surgical resection of primary squamous cell carcinoma of the oral cavity and oropharynx also undergo supraomohyoid neck dissection for staging of the negative (N(o)) neck. Dissection of the supraspinal accessory lymph node pad requires significant traction of the spinal accessory nerve. There are currently no data to indicate the incidence of metastases to this site and thus the necessity of performing dissection of these nodes. METHODS A prospective analysis of a consecutive series of 44 patients with newly diagnosed squamous carcinoma of the oral cavity or oropharynx undergoing surgical management of the primary lesion with staging neck dissection was performed. Patients underwent unilateral (41) or bilateral (3) supraomohyoid neck dissection with separate submission of the supraspinal accessory lymph node pad for pathologic evaluation to determine the incidence of nodal metastases. RESULTS A total of 15 patients (32%) had microscopic metastatic squamous cell carcinoma involving the supraomohyoid neck dissection specimen. Only 1 patient had a metastatic deposit involving the supraspinal accessory lymph node pad. This patient also had metastases in additional lymph nodes at level II. There was an equal incidence of metastases for all patients when stratifying by T stage. CONCLUSION This preliminary report reveals a small incidence of supraspinal accessory lymph node metastases in patients with T + NO squamous cell carcinoma of the oral cavity and oropharynx. We continue to accrue patients to determine if the incidence of supraspinal accessory lymph node metastases varies with an increased number of patients.

Abstract
BACKGROUND Understanding of differentiated carcinoma of the thyroid has improved in recent years with the definition of prognostic factors and risk group analysis. We intend to review our experience of differentiated thyroid cancer in relation to the risk of nodal and distant metastasis based on various histologic subgroups. METHODS This is a retrospective review of a consecutive series of 1,038 previously untreated patients with differentiated carcinoma of the thyroid treated over a period of 55 years. Univariate and multivariate analysis of various prognostic factors was performed. The incidence of nodal and distant metastasis was analyzed based on various histologic varieties of differentiated thyroid cancer. RESULTS There were 337 male and 701 female patients. The various histologic subgroups included papillary (810), follicular (169), and Hurthle cell cancer (59). The cumulative risk of nodal metastasis based on histological group was 61%, 30%, and 21% for papillary, follicular, and Hurthle cell variety, respectively. The risk of distant metastasis for the same histologic varieties was 10%, 22%, and 33%, respectively. The 5- and 20-year survival for these histologic subgroups was papillary (94% and 87%, respectively), follicular (87% and 81%), and Hurthle cell tumors (81% and 65%; P < 0.001). CONCLUSIONS The incidence of nodal metastasis is highest in the papillary subgroup; however, the incidence of distant metastasis was 33% in the Hurthle cell variety. The risk of nodal and distant metastasis varies considerably based on individual histologic variety.

Abstract
BACKGROUND The optimum management of the N0 neck remains controversial. When the neck is observed it is hoped that close follow-up will detect regional failure at an early stage. To test this hypothesis we examined patients undergoing therapeutic neck dissection for newly developed neck metastases during observation after treatment of the primary tumor. METHODS A retrospective chart review of 47 patients undergoing neck dissection for regional failure after surgical treatment of the primary tumor and observation of the neck from 1987 to 1992 was performed. The median time to failure in the neck was 13 months. RESULTS The clinical neck stage at the time of neck dissection was N1 in 37, N2A in 6, N2B in 1, and N3 in 3. However, pathologic staging revealed stages of N1 in 19, N2A in 5, N2B in 20, and N3 in 3. Extracapsular spread (ECS) was present in 23 patients (49%). Overall 36 patients (77%) had adverse pathologic findings (N greater than 1 or ECS). CONCLUSIONS These data indicate that when observation is used for the neck at risk for metastasis, patients tend to fail with high stage disease in the neck. This supports the philosophy of elective treatment of the neck but cannot show whether elective treatment will improve survival.

Abstract
OBJECTIVE To determine the postoperative ocular function in patients undergoing anterior fossa craniofacial resection with preservation of the orbit. DESIGN Retrospective medical chart review of patients treated from January 1, 1973, to July 31, 1994. Median follow-up was 38 months (range, 1-210 months). SETTING Tertiary referral center. PATIENTS Fifty-eight consecutive patients undergoing anterior fossa craniofacial resection with orbital preservation for tumors involving the anterior skull base. MAIN OUTCOME MEASURES Assessment of orbital complications of treatment, need for further surgical intervention to correct these complications, and determination whether functional vision was retained at last follow-up examination, and tumor recurrence within preserved orbits. INTERVENTIONS Anterior craniofacial resection with orbital preservation. Postoperative radiation therapy was administered to selected patients. RESULTS Overall, 25 patients (43%) had some ocular sequelae of their treatment. This consisted of epiphora in 21 patients, diplopia in 8, vision loss in 6, and pain and enophthalmos in 2. Twelve patients required revision surgery consisting of dacryocystorhinostomy in 8, ectropion repair in 3, drainage of orbital mucocele in 1, and corneal transplant in 1. Ocular complications were more common and vision loss occurred only in patients treated with postoperative radiation therapy. Functional vision in the ipsilateral eye was retained in 50 of the 58 patients. CONCLUSIONS When the orbit is preserved during anterior fossa craniofacial resection, ocular sequelae are frequent and may require revision surgery. Functional vision can be preserved in most patients.

Abstract
BACKGROUND Supraomohyoid neck dissection (SOHND) has assumed increasing importance as a staging lymphadenectomy in patients with N(o) oral and oropharyngeal squamous cell carcinoma (SCC), as well as a potentially curative procedure in selected patients with limited metastatic disease in the neck. METHODS Retrospective chart review of 287 patients who had a total of 320 SOHND for SCC between 1986 and 1993 as a follow-up to an earlier report that covered our experience between 1980 and 1985. After excluding 24 patients who also had local recurrence, or a new primary, the remaining 296 SOHND were assessed for the effectiveness of tumor control in the neck. RESULTS Of 248 elective SOHND, clinically negative nodes proved histologically positive in 60 patients (25%), only 4 of whom failed in the neck (7%). A total of 48 patients (16%) had a therapeutic SOHND for limited N+ disease, confirmed pathologically in 31, with neck recurrence documented in 2 (6%). Nodes proved negative histologically in 205 patients, 10 of whom failed in the neck (5%). Nine of the 16 patients with neck recurrence had received postoperative radiation therapy and 9 recurred within the field of the SOHND. CONCLUSIONS SOHND is a reliable staging procedure in patients with N(o) oral or oropharyngeal SCC. Therapeutic SOHND, in conjunction with postoperative radiation therapy, was highly effective in controlling neck metastases in carefully selected patients with limited disease in the upper neck.

Abstract
BACKGROUND Partial laryngectomy following previous irradiation is an oncologically sound procedure with excellent local control and survival rates. Several reports suggest an increased complication rate in previously irradiated patients. METHODS To analyze whether previous irradiation affected complications, disease control, or survival we performed a retrospective analysis of all patients who underwent vertical partial laryngectomy (VPL) for squamous cell carcinoma of the glottic larynx between January 1984 and August 1993. RESULTS Sixty-eight patients had adequate followup. The overall 5-year survival rates were 79% for previously treated patients and 95% for primary VPL patients (P = NS). The local control rates with surgical salvage were 93% and 98%, respectively. No increase in wound complications, time to decannulation, length of hospitalization, or ability to swallow were found. CONCLUSIONS VPL can be performed safely in selected patients following previous radiotherapy without a significant increase in complications or cost.

Abstract
BACKGROUND Surgical management of selected posterior pharyngeal wall lesions can be performed with pharyngectomy, allowing for larynx preservation, with radial forearm free flap (RFFF) reconstruction. METHODS Retrospective review of our experience using RFFF reconstruction in 9 patients. RESULTS All 9 patients had a posterior pharyngectomy with larynx preservation, neck dissection (3 bilateral, 6 unilateral), and RFFF reconstruction. Six patients experienced 8 postoperative complications including one postoperative death. Only 3 patients were able to obtain all nutrition orally. Tracheotomy decannulation occurred in 4 patients and voice was maintained in all patients. American Society of Anesthesiologists score (ASA) was an accurate predictor of postoperative medical complications. CONCLUSIONS Posterior pharyngeal resections with larynx preservation and RFFF reconstruction can be accomplished with acceptable morbidity in healthy patients with carefully selected lesions of the posterior pharyngeal wall. However, in patients with significant co-morbidities as reflected by an ASA of 3 or more, larynx preservation and RFFF reconstruction was fraught with significant morbidity and is not recommended.

Abstract
BACKGROUND Our understanding of the natural history of differentiated thyroid carcinoma has improved with the definition of prognostic factors. These prognostic factors have helped us identify patients in various risk groups. METHODS A retrospective review of a consecutive series of 810 previously untreated patients with papillary carcinoma of the thyroid was undertaken to analyze the prognostic factors and risk groups. There were 403 patients in the low-risk group, 313 in the intermediate group, and 94 classified in the high-risk group. RESULTS With a median follow-up of 20 years, 99% survival was achieved in the low-risk group, whereas only 43% survived in the high-risk group. The intermediate-risk group had a 20-year survival of 83%. The favorable prognostic factors included female sex, young age, absence of distant metastases and extrathyroidal extension of the disease, size < 4 cm, and low-grade histology. Focality, presence of lymph node metastasis, and pure papillary or mixed variant had no statistical significance on prognosis. CONCLUSIONS Based on various prognostic factors, low-, intermediate-, and high-risk groups are identified. Patients in the low-risk group have excellent survival (99%). Appropriate selection of surgical and adjuvant treatment should therefore be used based on prognostic factors and risk group stratification.

Abstract
BACKGROUND Although the standard therapy for locally advanced hypopharyngeal cancer remains surgery and postoperative radiotherapy (RT), alternative treatment approaches include induction chemotherapy and RT. The purpose of this retrospective study was to compare the long-term outcome of these treatments performed in a single institution. METHODS Twenty-six patients with advanced, resectable, squamous cell carcinoma of the hypopharynx were treated with induction chemotherapy and definitive RT (group I), reserving laryngectomy for salvage. The induction phase of therapy consisted of 2-3 cycles of cisplatin-based chemotherapy followed by conventional fractionated RT to doses of 66-70 Gy. The outcomes of this group of patients were compared with the outcomes of 30 patients with hypopharyngeal cancer who were treated at our institution with surgery and postoperative RT (group II). The median follow-up times of the surviving patients in groups I and II were 5 and 9 years, respectively. RESULTS The local recurrence-free survival at 5 years from the completion of therapy for group I was 50%, compared with 69% for group II (p = .41). Among patients with T3-T4 primary tumors, the 5-year local control rates were 58% and 59% for groups I and II, respectively (p = .78). The likelihood of larynx preservation, free of local disease at 5 years for group I, was 52%. The 5-year neck recurrence-free survival for groups I and II were 47% and 69%, respectively (p = .66). Among patients with N2-N3 stage disease, the 5-year incidence of neck failure for groups I and II were 73% and 68%, respectively (p = .74). The 5-year distant metastases-free survival for groups I and II were 67% and 57%, respectively (p = .19). The 5-year disease-free survival rates for groups I and II were 30% and 42%, respectively (p = .9). The 5-year overall survival rates for groups I and II were 15% and 22%, respectively (p = .65). CONCLUSIONS Nonsurgical therapy for advanced stage hypopharyngeal cancer provides survivorship comparable with that achieved with standard approaches of surgery and postoperative RT. However, despite the therapy, the outcome is poor. Future studies will need to explore new treatment strategies in an effort to improve upon the outcome for this group of patients.

Abstract
BACKGROUND The psychosocial adaptation of patients who had undergone a resection of the maxilla for cancer of the maxillary antrum and/or hard palate with the placement of an obturator prosthesis to restore speech and eating function was studied. METHODS Forty-seven patients were interviewed who had a maxillectomy with an obturator prosthesis at Memorial Sloan-Kettering Cancer Center, an average of 5.2 years (SD = 2.4 years) ago, 94% of whom had some of their soft palate resected. Interviews were conducted by telephone by a trained research interviewer, using a series of questionnaires to assess their satisfaction with the functioning of their obturator, and the psychological, vocational, family, social, and sexual adjustment. Measures included the Obturator Functioning Scale (OFS). Psychosocial Adjustment to Illness Scale (PAIS), Mental Health Inventory (MHI), Impact of Event Scale, and Family Functioning Scale. RESULTS Using multiple regression and discriminant function analyses, satisfactory functioning of the obturator prosthesis, as measured by the OFS, was found to be (1) the most highly significant predictor of adjustment, as measured by the PAIS (p < .0001) and the MHI Global Psychological Distress Subscale (MHI-GPD) (p < .001), and (2) significantly related to their perception of the negative socioeconomic impact of cancer upon their lives. The most significant predictor of better obturator functioning were the extent of resection of their soft palate (one third or less, p < .001), and hard palate (one fourth or less, p < .01). Specific aspects of obturator functioning that most significantly correlated with better adjustment (PAIS, MHI-GPD) were: less difficulty in pronouncing words (r = .40 and r = .51, respectively, p < .01), chewing and swallowing food (r = .27-.46, p < .05), and less change in their voice quality after surgery (r = .52 and r = .56, respectively, p < .001). CONCLUSIONS These findings suggest that a well-functioning obturator significantly contributes to improving the quality of life of maxillectomy patients.

Abstract
BACKGROUND Cervical lymph node metastasis in differentiated thyroid carcinoma has mostly been found to have little relationship to prognosis. However, some studies report nodal involvement to be an adverse factor, while others have found it to be favorable. We have undertaken a matched-pair analysis of previously untreated patients, with and without ipsilateral neck metastasis, to examine the significance of nodal spread in patients with otherwise equivalent prognostic factors for differentiated thyroid cancer. METHOD From a database of 931 patients, treated from 1930 to 1980, we used a computer to match patients with confirmed lateral neck metastasis (N1) to those who were stage NO, and had the following identical prognostic factors: no distant metastasis, age (within 4 years), and tumor size, histology, and intrathyroidal extent. When possible, matches were also made for gender, multifocality, and extent of thyroid surgery. Survival and treatment failures were analyzed, with and without stratification for age. RESULTS We were able to select 100 N1 patients with corresponding NO patients, sharing the major prognostic risk factors as listed. Overall, there was no difference in survival, although N1 patients more often had recurrence. Mortality increased with age. Analysis at high-risk age (45 years and older) showed significantly more recurrences in N1 patients (p = .008). Twenty-year survival in N1 patients over the age of 45 was lower than that of NO patients. On the other hand, under the age of 45, N1 patients had better survival. These differences, however, did not reach statistical significance. CONCLUSION Nodal involvement in older patients with thyroid cancer increases the risk of recurrence, although no significant difference in survival is observed in relation to age.

Abstract
BACKGROUND Although long-term cures have been achieved for locally advanced squamous cell carcinomas of the head and neck, there is a paucity of information available regarding patients' perspectives of their functional outcome. PATIENTS AND METHODS Thirty-five long-term survivors free of disease following surgery and postoperative radiotherapy for advanced cancers of the oral cavity and oropharynx were sent questionnaires to evaluate their long-term functional outcome after therapy. The questionnaires included a subjective performance status scale that assessed the patient perceived (1) ability to eat in public, (2) understandability of speech, and (3) normalcy of diet. Twenty-nine of 35 patients participated in this function assessment and are the subjects of this report. RESULTS The mean function scores for all patients were as follows: 72 for eating in public, 69 for understandability of speech, and 58 for normalcy of diet. Functional results were further analyzed by T stage and anatomic subsite. Inferior results were noted with increasing T stage. A two-way analysis of variance showed that this difference was significant even after adjusting for the effect of anatomic subsite (P = 0.0002, P = 0.018, and P = 0.0018 for the three outcome variables). In addition, patients with base of tongue lesions had a worse functional outcome for both early T state (T1/T2) and advanced T stage (T3/T4) when compared to other subsites. This difference averaged across T stage was statistically significant for understandability of speech (P = 0.0019) and normalcy of diet (P = 0.013), but was not significant for eating in public (P = 0.16). CONCLUSIONS This performance status scale was found to be a useful tool for functional assessment following definitive therapy for advanced stage head and neck carcinomas. These subjective functional scores deteriorated with increasing T stage. In addition, functional scores for oral tongue, floor of mouth, and tonsillar primaries were superior to those for base of tongue lesions. These functional outcome scores are consistent with the extent of surgery required for the base of tongue subsite and are in direct relation to the patients' T stage in this study population.

Abstract
BACKGROUND The understanding of prognostic factors has facilitated stratification of risk groups in differentiated carcinoma of the thyroid. The prognostic factors have clearly identified the risk groups as low, intermediate, and high risk. Risk group categorization has facilitated a selective surgical approach for thyroid carcinoma. METHODS A retrospective review of 228 patients with follicular carcinoma of the thyroid was undertaken. Various prognostic factors and risk groups were analyzed. Univariate and multivariate analyses were performed, and the survival curves were plotted by the Kaplan-Meier method. Fifty-nine (26%) patients presented with Hürthle cell histology. The risk groups revealed 62 patients in the low, 84 in the intermediate, and 82 in the high risk groups. RESULTS The 10-year survival for low, intermediate, and high risk groups was 98%, 88%, and 56%, respectively, and the 20-year survival for the same groups was 97%, 87%, and 49%, respectively. Adverse prognostic factors included age older than 45 years (p < 0.001), Hürthle cell variety (p = 0.05), extrathyroidal extension, tumor size exceeding 4 cm, and the presence or absence of distant metastasis (p < 0.001). Gender, focality, and presence of lymph node metastasis had no significant impact on prognosis. CONCLUSIONS Patients in the low risk group have excellent survival, whereas the high risk group behaves poorly. Appropriate selection of treatment for the primary disease and adjuvant therapy should be considered on the basis of the prognostic factors and risk group analysis.

Abstract
From 1983 to 1991, 31 patients underwent salvage laryngectomy for persistent or recurrent squamous carcinoma of the larynx (14), hypopharynx (15), or oropharynx (2) as part of a larynx preservation protocol. Laryngectomy was performed as a consequence of poor response to induction chemotherapy in 13 and for recurrent disease after completion of chemotherapy and irradiation in 18. Postoperative pharyngocutaneous fistula occurred in 39%, resulting in prolonged hospitalization. Local control was achieved in 68%, more often in patients with laryngeal as opposed to nonlaryngeal primaries (86% versus 53%; p = .05). The overall actuarial survival and disease-specific survival at 2 years were 32% and 38%, respectively. Disease-specific survival at 2 years was better in patients with laryngeal as compared to nonlaryngeal primaries (56% versus 24%; p = .02). There were no long-term survivors among the nonlaryngeal primary patients. In selected patients in whom larynx preservation failed, salvage laryngectomy was associated with acceptable local control and survival. Palliation was obtained in patients who were not cured by their laryngectomy. Future investigation will focus on identification of factors predicting complications and strategies to reduce the incidence and severity.

Abstract
BACKGROUND We have analyzed our experience with differentiated thyroid cancer patients with extrathyroidal extension (ETE) to investigate patterns of recurrence and define factors that predict failure. PATIENTS AND METHODS The records of 1,012 patients treated surgically from 1930 to 1985 were reviewed. A total of 79 patients (8%) had ETE. The median length of follow-up was 10 years. RESULTS Patients with ETE were more likely to fail treatment and to die of their disease than were patients without ETE (77% versus 34% and 71% versus 13%, respectively; P < 0.0001). Local, regional, and distant failures were more prominent among patients with ETE than among those without ETE (48% versus 9%, 41% versus 16%, and 37% versus 11% respectively; P < 0.0001). Survival of patients with ETE was adversely affected by nonpapillary histology, distant metastasis, age > 45, tumor size > 4 cm, and incomplete excision (P < or = 0.05). After stratification for age, survival in older patients was not affected by tumor size or incomplete excision, while in younger patients tumor size or the presence of distant metastasis did not adversely affect survival. Patients younger than 45 with negative margins had similar survival to patients without ETE (P = 0.46). CONCLUSIONS Patients with ETE are more likely to die of their disease and to fail at all sites. Survival in older patients was not affected by incomplete excision while it was in younger patients. The presence of distant metastasis did not affect survival in younger patients. Our results suggest that among patients under 45, the presence of ETE does not adversely impact upon survival when the primary tumor is completely resected.

Abstract
BACKGROUND The survival of patients with carcinoma of the cervical esophagus remains poor in spite of multimodality treatment and technical improvements in surgical resection and reconstruction. This study was undertaken to update our experience with cervical esophageal carcinoma and to identify factors that had an impact on patient survival and quality of life. PATIENTS AND METHODS Clinical data encompassing 132 variables were collected on 67 patients with cervical esophageal carcinoma from 1980 to 1993. Statistical analysis was performed: independent Student's t-tests, Cox regression, Kaplan-Meier curves, and log rank analyses were used in the statistical evaluation. The mean age of the patients was 63 years (range 31 to 88). Dysphagia was the primary symptom in 86% of patients; 80% had received no prior treatment. The most common abnormal finding (21%) on physical examination was a neck mass. RESULTS Curative resection was performed in 22 patients, 7 had palliative procedures, and 7 were found to be inoperable at exploration and received palliative treatment. Radiation with or without chemotherapy was definitive treatment for 10 patients, whereas 4 patients were treated with chemotherapy alone for cure, and 17 patients received palliative treatment. The mean survival following diagnosis was 17 months (range 1 to 96). Cumulative 5-year survival was 12%. CONCLUSIONS Persistent disease, chemotherapy prior to presentation, and chemotherapy for cure remained as statistically significant parameters associated with decreased survival by multivariate analysis. There was a trend toward improved survival in patients treated with surgical resection.
