Anatomical location defines distinct molecular subtypes of mucosal melanoma.

BACKGROUND: Mucosal melanoma (MM) is a rare and aggressive melanoma subtype that is understudied. The relationships between anatomical location, genomic alterations, stage at presentation, and survival remain incompletely characterized. METHODS: We carried out a retrospective single tertiary center study of 105 patients with histologically confirmed MM diagnosed between 1996 and 2025. Clinical and genomic data were analyzed to evaluate associations between anatomical location, mutational profile, stage at presentation, and survival outcomes, including melanoma-specific mortality. RESULTS: Lower-body tumors arising in the anus or genital areas were enriched for KIT and splicing factor 3 subunit B1 alterations, whereas NRAS mutations were distributed across anatomical regions. Among the two most common mutated genes, NRAS-mutant tumors were more likely than KIT-mutant tumors to present with metastatic disease [53% versus 19%; P = 0.046, odds ratio (OR) 4.7, 95% confidence interval (CI) 1.15-19.41]. Lower-body tumors were associated with worse overall survival (OS) than upper-body tumors (median 2.81 versus 8.40 years; OR = 0.05) and with higher melanoma-specific mortality. In multivariable analyses, upper-body location remained independently associated with improved OS (hazard ratio 0.14, 95% CI 0.05-0.36, P < 0.001). CONCLUSIONS: Anatomical location of MMs and genomic alterations define biologically and clinically distinct subtypes.

The predictive value of lymphoscintigraphy for nodal metastases of cutaneous melanoma.

Lymphoscintigraphy is used to identify ambiguous drainage patterns in cutaneous melanoma of the head, neck and trunk. This study evaluated the efficacy and reliability of lymphoscintigraphy to identify the drainage nodes in 51 patients undergoing both elective and therapeutic lymphadenectomy over a seven-year period. All 13 patients who had lymph node metastases during this follow-up period had the metastatic disease in the very lymph node basins identified by lymphoscintigraphy. Most significantly, none of the 51 patients had metastatic disease in lymphatic basins that were not previously identified by lymphoscintigraphy.

Breast reconstruction in previously irradiated patients using tissue expanders and implants: a potentially unfavorable result.

There exists a paucity of definitive information on the suitability of implant reconstructions in previously irradiated breast cancer patients. This controversial topic prompted a review of our prosthetic reconstructions in this select group of patients. A retrospective study of patients treated between 1976 and 1993 with lumpectomy and radiation therapy for early breast cancer revealed 67 patients with local recurrences. Nine of these patients (10 breasts) underwent a two-stage prosthetic reconstruction following a salvage mastectomy. The average age was 47.9 years. The mean dose of irradiation was 6,070 cGy. The average interval from radiation therapy to placement of a tissue expander was 4.6 years. In one patient (10%) the tissue expander extruded. The average follow-up for 8 patients (9 breasts) who underwent exchange to a permanent prosthesis was 5.1 years. In four reconstructions (40%) there was an uneventful postoperative course. Two cases (20%) were difficult to expand and the final result lacked projection. One patient (10%) developed an infection requiring removal of the permanent prosthesis. Two patients (20%) developed Baker class III or IV capsular contractures. Overall, in our group of 10 implant reconstructions, 60% of the patients resulted in either a complication or an unfavorable result.

Safety and efficacy of isolated perfusion of extremities for recurrent tumor in elderly patients.

BACKGROUND: The treatment of bulky recurrent melanotic lesions of extremities with isolated limb perfusion with high dose chemotherapy offers palliation in a number of patients. However, the question is raised whether these major surgical procedures are too risky to warrant performing them in elderly patients. METHODS: Sixty-seven limbs were perfused in 60 patients with various drugs from 1976 through 1996 (35, imidazole carboxamide; 7, cisplatin; 20, carboplatin; 5, thiotepa). Among the 67 perfusions, 20 were in patients aged 70 years and older. Perfusion was performed for 16 upper extremities and 51 lower extremities by using the pump oxygenator for 1 hour. RESULTS: A total of 19 complications were noted after a total of 14 of the 67 perfusions (21%) (postoperative edema, 5; seroma, 4; wound separation or infection, 9; nonfatal pulmonary embolus, 1). The complications in 4 of 20 perfusions in the older patients (20%) were less than in 15 of 47 perfusions in the younger patients (32%). Among the 17 patients older than 70 years of age who were treated with perfusions for recurrent disease, four patients (24%) are alive with no evidence of disease (NED) for a median of 29 months (range, 16 to 80 months); one patient is now more than 6 years with NED after her third perfusion for repeated in-transit disease. Another 2 of 17 patients (12%) are alive with disease for a median of 89 months (range, 54 to 123 mos). The remaining 11 patients (64%) are dead of their disease. These data are comparable to the control rates in the group of younger patients in the study. Overall, half of all the patients (14 of 28) who died of their disease in both groups had maintained local control of their involved extremities. CONCLUSIONS: Aggressive treatment in selected patients with regional isolated perfusion of limbs for melanoma can lead to significant palliation of symptoms and salvage of limbs with adequate disease-free control and occasional survival benefit. This series of patients was associated with meaningful disease control and with few serious complications. Perfusions are tolerated well by patients in their 70s and 80s; therefore advanced age is not a contraindication to this procedure in carefully selected patients.

Patterns of care for cancer of the larynx in the United States.

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.

Restructuring academic departments of surgery at university medical centers.

BACKGROUND: The present administrative and financial structures of clinical departments in most medical schools date back to the beginning of the 20th century when changes were brought about as a result of the Flexner report. Since that time, there have been significant changes in the health care industry that compel us to reevaluate our goals in order to meet the needs of the 21st century. METHODS: This paper proposes that we need to consider the administrative restructuring of our departments from the vertical hierarchical system to the horizontal matrix system in order to facilitate cost-effective use of our manpower as well as facilities. It also proposes a financial restructuring of the departments to cut the costs of billings and collections of the clinical practice, to develop a long-term program to raise departmental endowments, and to develop an effective incentive plan. RESULTS: A novel mechanism is proposed to provide "stock options" for the faculty. Such a system would reward academic and clinical productivity, retain productive faculty, and offer options for those who are not productive. CONCLUSIONS: In order to flourish in the health care marketplace, academic programs must be willing to promote a change in the culture of the departments and adapt to a more business-oriented environment.

Hypopharyngeal cancer patient care evaluation.

A survey was conducted to identify demographics and standards of care for treatment of hypopharyngeal squamous cell carcinoma in the United States. Data were accrued from voluntary submission of cancer registry and medical chart information from 769 hospitals representing 2939 cases diagnosed from 1980 to 1985 and 1990 to 1992. Clinical findings, diagnostic procedures employed, treatment practices, and outcome are presented. Overall, 5-year disease-specific survival was 33.4%, which segregated to 63.1% (stage I), 57.5% (stage II), 41.8% (stage III), and 22% (stage IV). Survival was best for patients treated with surgery only (50.4%), similar with combined surgery and irradiation (48%), and worse with irradiation only (25.8%). This analysis provides a standard to which current treatment practice and future clinical trials may be compared.

Further experiences with the sternocleidomastoid myocutaneous flap: a clinical appraisal of 31 cases.

This paper evaluates the experience of one surgeon with use of the sternocleidomastoid myocutaneous flap in 31 consecutive reconstructions in the oropharyngeal area. While the complication rate was 52 percent, essentially all were due to partial epidermal losses. All flaps healed without requiring additional surgery. A review of each of the cases to evaluate the impact of previous radiation therapy, location of the blood supply, or concomitant neck dissection did not identify any differences in the groups. I conclude that this regional flap is readily available and is still useful in selected patients needing reconstruction of small wounds in the oropharyngeal area.

The transverse platysma myocutaneous flap for head and neck reconstruction.

This paper reports the platysma myocutaneous flap that has been modified to be directed transversely across the midportion of the neck, with its blood supply from the posterior cervical triangle. Seven flaps have been used to reconstruct wounds of the ear, cheek, and lips in six patients. One flap had a partial skin paddle loss when the flap was harvested from the neck of a patient who had had two previous surgical wounds to the neck and may represent an alteration of the blood supply secondary to surgical scarring. The remaining six flaps were robust, and all healed without complications.

Regional isolated perfusion of extremities for melanoma: a 20-year experience with drugs other than L-phenylalanine mustard.

Recurrent melanoma of the extremities can lead to bulky symptomatic lesions that become difficult management problems. Treatment of these tumors with isolated limb perfusion with high dose chemotherapy may offer palliation in a number of patients. Unfortunately, the most commonly used drug, L-phenylalanine mustard, has been known to have significant associated tissue toxicity. Therefore, during the years 1976-1995, we perfused 67 limbs in 60 patients with various other drugs: 36 with dimethyltriazeno imidazole carboxamide, 6 with cisplatin, 20 with carboplatin, and 5 with thiotepa). Perfusion was performed for 16 upper extremities and 51 lower extremities using the pump oxygenator for 1 hour. Among the 60 patients, 17 were treated prophylactically for high-risk melanoma, whereas 43 were treated for local and in-transit recurrences. The technique of perfusion successfully isolated the limbs from the systemic circulation: the median leaks over time were 0.5-1.6 percent for the upper extremities, and 0.2-7.5 percent for the lower extremities. Among the 43 patients treated with therapeutic isolated limb perfusion, 11 patients (26 percent) are alive with no evidence of disease for a median of 58 months (range: 8 months to 17 years 9 months), and another 5 patients (12 percent) are alive with recurrence for a median of 45 months (range: 27 months to 10 years 7 months). Four patients required two perfusions, and two patients required three perfusions (one patient has no evidence of disease 6 years after her third perfusion for recurring in-transit disease). There were 19 complications noted after 14 of the 67 perfusions (21%): postoperative edema, 5; seroma, 4; wound separation/infection, 9; and nonfatal pulmonary embolus, 1. In our experience, aggressive treatment in selected patients with regional isolated perfusion of limbs for melanoma has provided meaningful palliation and salvage of the limbs with adequate disease-free control, and occasional survival benefit. This regional treatment modality is associated with meaningful control and with few serious complications, especially when compared with studies using L-phenylalanine mustard. This series illustrates the safety of controlling limb recurrence with this technique, even with repeat perfusions in the same patient.

Reconstruction of the head and neck.

The collaboration of surgeons, radiation oncologists, chemotherapists, dentists, oral surgeons, prosthodontists, and speech therapists has led to major advances in the management of the difficult cancers of the head and neck area. The advent of myocutaneous flaps and the facilitation of microsurgical free flaps have ushered in an era of one-stage reconstructions to shorten the hospital stay and improve the overall therapeutic, functional, and cosmetic results.

Prolonged survival in patients with advanced melanoma treated with neoadjuvant chemotherapy followed by resection.

Patients with metastatic melanoma (AJCC stage IV) generally have a very poor prognosis (median survival, 6-8 months). Combination chemotherapy is often the treatment of choice. Despite the higher response rates of a number of new combination regimens, the median duration of response ranges from 6 to 9 months, with no significant survival advantage. To evaluate whether surgical resection of residual metastases after chemotherapy can improve survival, we conducted a retrospective analysis of all patients enrolled on various chemotherapy protocols for metastatic melanoma at Yale between March 1987 and March 1993. We identified 16 patients who underwent surgical resection of residual disease after receiving one to four cycles of combination chemotherapy. Sites of metastases included regional and distant lymph nodes, skin, subcutaneous tissue, lung, and liver. No patients had brain or bone metastases at the initiation of therapy and performance status (PS) was 0.1. Follow-up for these 16 patients ranges from 14 to 62 months (median, 35 months) from the start of chemotherapy. All 16 patients had either complete responses (CR = 3) or partial responses (PR = 7), or stable disease (SD = 6) after chemotherapy. Eleven patients are currently alive; 10 remain free of disease. A comparison group (control) of 14 patients was identified from the same retrospective analysis using similar clinical characteristics such as sites of metastases, PS, and cycles of chemotherapy. No patients underwent surgical resection either because of patient refusal or concomitant medical problems. None had evidence of disease progression (CR = 3, PR = 2, SD = 9) at the completion of chemotherapy. However, duration of survival in this group from the start of chemotherapy ranged from 4 to 45 months (median, 11.5 months). Twelve patients have died and 2 are currently alive, 1 of which has recurrent disease. Based on the comparison of these two groups, this report suggests that patients treated with neoadjuvant chemotherapy may benefit from surgical resection of residual metastases, and this approach should be studied further.

General principles of reconstruction following cancer surgery.

The evolution and development of the fields of surgery, radiation therapy, and chemotherapy have led to the collaboration of these specialties in the management of cancer patients. The multidisciplinary approach to the treatment of cancer has led to better cure rates for the patients with the least risk for disabilities.

Combined Modality Therapy

Reconstructive surgery in melanoma patients.

The treatment of malignant melanoma should include a wide resection, the extent of which should be based on the tumor thickness of the primary site as well as the anatomic site of the location of the tumor. The various methods of reconstruction of these donor sites may include primary closure, split-thickness skin grafting, full-thickness skin grafting, or a number of local flaps. Each of these techniques is selected based on the size and extent of the wound necessitated by the wide excision. The concept that needs to be kept in mind is that the surgical treatment for a melanoma should be as wide as is indicated based on the depth of invasion, which is an indication for the potential of local recurrence. The areas should be treated most often with flaps to allow for early ambulation, decreased disability and cost of hospitalization, and improved functional and cosmetic results in the long term for the patient. It is my personal belief that with further experience in the use of these various flaps, surgeons will be able to provide secure wide surgical excisions of many sizes with greater confidence, because these areas can be resurfaced without disability. In this fashion, the extent of the surgical excision no longer should be a compromise for fear of difficulty in closing or resurfacing the wounds.

The association between melanoma, lymphoma, and other primary neoplasms.

BACKGROUND AND OBJECTIVE: Reports of multiple primary tumors are not new. However, we have noted a disproportionate number of patients with melanoma in whom lymphoma develops and wanted to define the incidence of this association. DESIGN: All 664 patients with melanoma treated at Yale-New Haven Hospital, Conn, during the 5-year period from 1986 to 1991 were reviewed. The incidence of all the associated malignant neoplasms among our patients with melanoma was compared with the incidence that would be expected in the normal population adjusted for age, race, and sex. RESULTS: Among the 664 patients, 54 (8.1%) had one or more additional malignant neoplasms. Of the 10 different malignant tumor types recorded, lymphomas were the most prevalent. This incidence of lymphoma among the melanoma patients was 12 of 664, resulting in an incidence of 548 per 100,000 population, 16 times higher (P < .0125) than the expected incidence (34 per 100,000) when adjusted for age, sex, and race. CONCLUSIONS: The incidence of a second malignant neoplasm in our patients with melanoma was 8.1%. Lymphoma was a particularly common type of second malignancy, showing an incidence more than 16-fold higher than that expected in the normal population. It is particularly important, from a clinical point of view, to be aware of this when clinically palpable lymph nodes develop in areas not normally the site of regional lymphatic drainage of the primary melanoma.

Multiple primary melanomas: data and significance.

Cancer statistic reports show that the incidence of melanoma has increased each decade. It is now estimated that approximately 5 percent of the patients with primary cutaneous melanoma will develop another primary melanoma in their lifetime. This report describes the information gathered from 27 patients at the Yale Melanoma Unit who have developed 59 individual primary melanomas; 22 of the patients developed a second primary melanoma, and 5 patients each developed three primary melanomas. In 8 patients (30 percent), the second primary melanoma was diagnosed within 1 month of the first malignancy and was considered synchronous. The remaining 24 melanomas in the 19 patients presented subsequently: 4 (17 percent) within the first year, 7 (29 percent) during the second year, and 13 (54 percent) beyond the second year of the first diagnosis. Although the thickness of the initial melanoma ranged from 0.2 to 6.0 mm, all subsequent melanomas were either in situ or less than 1.0 mm in thickness. This study shows that patients who developed more than one melanoma invariably had thin subsequent lesions. The implications of the multiple melanomas are not a poorer prognosis, but rather that the patients' prognosis is the same as that of the original, or thickest, melanoma.
