RESUMO

Many years ago, planned giving was characterized as low key and troubled by a lack of closure. Today, planned giving officers are feeling the pressure that all fund raisers face for immediate fund-raising results and more aggressive fund-raising methods.

RESUMO

Osteoradionecrosis of the jaws is a severe complication of radiotherapy in the treatment of the head and neck neoplasms. The literature indicates a recent decline in the reported incidence of this complication. The purpose of this study was to further assess the incidence rate for osteoradionecrosis. Factors previously associated with an increased risk for osteoradionecrosis were evaluated to determine possible relationships. A retrospective chart review was conducted for 193 patients treated with radiotherapy for malignant head and neck tumors over an eight-year period. Recorded diagnoses of osteoradionecrosis were noted. Factors previously correlated with the development of osteoradionecrosis were assessed. Of the 193 charts reviewed, 9 diagnoses of osteoradionecrosis of the jaws were made representing an incidence rate of 4.7% for the period evaluated. No single factor was noted to be associated with the development of osteoradionecrosis. The results indicate a low incidence rate for osteoradionecrosis as a post-radiation treatment complication. No single causative factor could be identified suggesting a multifactorial interaction responsible for osteoradionecrosis.

RESUMO

This retrospective study evaluated the use of percutaneous craniofacial implants for the prosthetic rehabilitation of patients with a history of orbital exenteration and irradiation for oncologic tumors of the head and neck. A total of 24 implants were placed in six patients. All implants were determined to be osseointegrated at the time of uncovering. Three implants were subsequently resubmerged beneath the soft tissue because of positional interferences with prosthesis fabrication. The remaining 21 implants were ultimately used to retain six orbital prostheses. Two implants failed to maintain osseointegration during the follow-up period and were subsequently removed without complications. This represents an overall integration success rate of 90.5% over a mean follow-up period of 32.8 months (range = 11 to 68 months). The significance of these findings and their relationship to comparable reports in the literature are discussed.

RESUMO

OBJECTIVE: To evaluate the use of endosseous transcutaneous implants to retain removable facial prostheses for the rehabilitation of orbital defects. SETTING: Tertiary referral center. PATIENTS: Six patients with a history of facial defects secondary to orbital exenteration for cancer ablation. OUTCOME MEASURES: Clinically noted functional and cosmetic results, patient reports of satisfaction, and complications encountered. RESULTS: Twenty-three of 25 implants were integrated (postoperative period, 13 to 65 months; mean, 44.2 months), representing an integration success rate of 92%. All patients were successfully wearing implant-retained prostheses after 48.3 months (post-prosthesis delivery period, 1 to 48.3 months; mean, 24.5 months). Overall patient satisfaction was very high. CONCLUSIONS: Implant-retained prosthetics represent a safe and effective treatment option. It is anticipated that this treatment will become the standard of rehabilitative care for patients with orbital defects.

RESUMO

Craniofacial implants have been used successfully for the retention of facial prostheses. However, complications occur that can lead to the loss of implant integration. One such complication is infection possibly resulting from crevicular microflora activity. As part of an ongoing study, samples from crevicular sites surrounding 17 craniofacial implants were collected and submitted for microbiological assay. The results demonstrated the presence of opportunistic pathogens in many sites regardless of subjects' hygiene efforts. The significance of the findings is reviewed.

RESUMO

PURPOSE: To determine survival rates and the pattern of failure in head and neck cancer patients treated with induction chemotherapy, limited surgery and concomitant chemoradiotherapy. PATIENTS AND METHODS: Three cycles of induction chemotherapy with cisplatin, fluorouracil (5-FU), leucovorin, and interferon alfa-2b (PFL-IFN) were followed by optional surgery, and seven or eight cycles of 5-FU, hydroxyurea, and concurrent radiation for 5 days (FHX) for a total radiation dose of 65 to 75 Gy. Surgical resection was performed with the intent to spare organ function. RESULTS: Seventy-one patients were treated at three institutions. Sixty-five patients (91%) had stage IV disease with N2/3 in 46. Thirty-three patients (51%; 95% confidence interval, 39% to 63%) achieved a clinical complete response (CR) to PFL-IFN. Local therapy consisted of surgery in 37 and/or FHX in 55 patients. With a median follow-up duration of 37 months, there have been 20 recurrences (15 local, four distant, and one both local and distant), and 29 deaths, 15 in patients with disease progression and 14 not directly related to the primary tumor. Four patients have developed second malignancies. At 3 years, 69% (+/- 6%) are progression-free and the overall survival rate is 60% (+/- 6%). Toxicity of PFL-IFN included severe or life-threatening mucositis (54%) and myelosuppression (60%). Five patients died of toxicity. During FHX, 70% of patients had grade 3 or 4 mucositis. CONCLUSION: PFL-IFN is highly active, producing clinical CRs in 51% of patients, and, when followed by FHX, resulting in high local and distant control and overall survival rates. Second malignancies and intercurrent medical disease emerge as major risks to long-term survival. In view of the high toxicity and long treatment duration, further modifications of this approach are required.

RESUMO

Review of the otolaryngologic literature reveals no case reports of mycosis fungoides involving the esophagus. Post-mortem studies report 12 cases of esophageal involvement in 131 autopsies of patients with mycosis fungoides. We describe a 54-year-old man with mycosis fungoides involving the larynx, hypopharynx, and esophagus. Treatment consisted of radiation to this area, with resolution of the patient's hoarseness and dysphagia. The charts of 96 patients with mycosis fungoides treated at our institution were retrospectively reviewed. Three additional cases involving the aerodigestive tract, but not the esophagus, were found. Esophageal mycosis fungoides was an incidental finding in two of seven autopsies at our institution.

RESUMO

To increase the complete remission (CR) rate achieved with two cycles of cisplatin, continuous infusion fluorouracil (5-FU) and oral leucovorin (PFL) we added two antifolate drugs, methotrexate (MTX) and the lipophilic piritrexim (PTX), to the combination (PFL-MP). Twenty-eight patients with previously untreated Stage IV squamous cell carcinoma of the head and neck received 2 cycles of cisplatin 100 mg/m2 on day 1 followed by a 5-day continuous infusion of 5-FU at 800 mg/m2/day and 100 mg of leucovorin administered orally every 4 hours. MTX was administered at 40 mg/m2 IV on day 15 and PTX at 75 mg orally twice daily on days 22 to 26, with cycle 2 starting on day 36. After 2 of the first 5 patients had tumor progression between days 15 and 35, the regimen was intensified to MTX 50 mg/m2, PTX 100 mg twice daily and a cycle duration of 28 days. Local therapy consisted of surgery and/or radiotherapy with concomitant 5-FU and hydroxyurea (FHX) administered every other week. Eleven patients (39%, 95% confidence intervals 21-57%) had a CR, 9 (32%) had a PR, and four patients had no response. Four patients were unevaluable for response to PFL-MP. Patients with poor performance status or N3 disease were less likely to achieve a CR. Mucositis following PFL was the dose-limiting toxicity. Local therapy included surgery in 15 patients and FHX chemoradiotherapy in 19 patients. The administration of FHX in this setting proved feasible and the regimen was given near the intended dose intensity in the majority of patients.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

In planned giving, 80 percent of the money comes from bequests and 20 percent from life income agreements. But fund raisers still spend most of their time pursuing the 20 percent.

RESUMO

The radiobiological parameters of 33 tumor cell lines were studied in biopsy samples obtained from patients prior to radiotherapy. Epithelial tumor cells derived from head and neck cancer patients were more radioresistant than tumor cell lines derived from patients with sarcoma regardless of method of analysis. The presence of radioresistant tumor cell lines was associated with local failure in some patients. However, the presence of radiosensitive tumor cells did not necessarily predict local control. Our data suggest radiocurability is complex and inherent radiobiological parameters of tumor cells may be only one factor in radiotherapy outcome.

RESUMO

Two regimens of neoadjuvant chemotherapy for previously untreated patients with locally advanced head and neck cancer were compared with the goal of identifying a regimen with a greater than 50% complete response (CR) rate. Patients with a performance status of 0 to 2 and normal end-organ function were randomized to receive either four cycles of neoadjuvant methotrexate, cisplatin, and continuous infusion 5-fluorouracil (5-FU) (MPF) (arm A), or four cycles of bleomycin, cisplatin, and methotrexate (PBM) alternating with cisplatin and 5-FU (PF) (arm B). Patients with a performance status of greater than 2 or a carbon monoxide diffusion capacity of less than 50% of the predicted value were assigned to the arm A regimen but were analyzed separately (arm C). Local therapy consisted of surgery (for patients with resectable disease) or radiation therapy followed by two cycles of adjuvant chemotherapy with the regimen that was administered initially. Of the 42 patients who were evaluated, 16 were randomized to arm A, 13 to arm B, and 13 to arm C. The clinical CR rate was 19% on arm A (95% confidence interval, 0% to 38%), 39% on arm B (95% confidence interval, 12% to 66%) (P = 0.41), and 54% on arm C (95% confidence interval, 27% to 81%). At a median follow-up time of 35 months, the 2-year actuarial survival rate was 61% on arm A, 69% on arm B (the P value was not significant), and 38% on arm C. The 2-year survival rate for all 42 patients who were treated was 57% and the median survival time was 31 months. Toxicities of neoadjuvant chemotherapy on all arms consisted of mild to moderate myelosuppression and renal toxicity. The incidence of moderate to severe mucositis was significantly higher on arm A than arm B (P = 0.02). Two cycles of adjuvant chemotherapy were administered to only 11 of 42 patients due to patient refusal or cumulative toxicity. In conclusion, both neoadjuvant chemotherapy regimens resulted in similar response and survival rates, but mucositis was more severe with arm A. However, since neither regimen was likely to cause a CR rate of greater than 50%, this study was closed to further patient accrual.

RESUMO

We studied epidermal growth factor receptor (EGFR) gene amplification and expression in 11 early passage human head and neck carcinoma cell lines. Three cell lines demonstrated EGFR gene amplification and 10 lines showed an increase in EGFR mRNA when compared with normal keratinocytes, placenta, and a human skin carcinoma cell line. The effects of EGF on growth in 6 head and neck carcinoma cell lines was also studied. Growth inhibition at a concentration of 20 ng/mL was observed in one cell line but had no effect on growth in 5 cell lines. An increase in EGFR may be important in the etiology of, or progression of, head and neck carcinoma although the mechanisms need to be elucidated by further study.

RESUMO

We studied the in vitro radiobiological parameters of 16 human head and neck squamous cell carcinoma tumor cell lines cultured from patients who suffered local failure after a curative course of radiotherapy. The radiobiological parameters determined included D0, n, and D. When compared with in vitro radiobiological parameters of tumor cells cultured from head and neck cancer patients prior to radiotherapy, human sarcoma cell lines, and normal human diploid fibroblasts studied in our laboratory (as well as other human tumor cell lines reported in the literature), tumor cells derived from radiotherapy failures on average are resistant to the cytotoxic effects of ionizing radiation.

RESUMO

To increase the complete response (CR) rate of patients with locally advanced head and neck cancer after three cycles of neoadjuvant chemotherapy, we added sequential methotrexate to the combination of cisplatin and continuous infusion fluorouracil (5-FU). We also evaluated the feasibility of administering three additional cycles of the same regimen as adjuvant chemotherapy. Thirty-eight patients were treated; the median age was 53 years and 36 patients had stage IV disease. Chemotherapy consisted of methotrexate 120 mg/m2 followed 24 hours later by cisplatin 100 mg/m2 and a five-day continuous infusion of 5-FU at 1,000 mg/m2/d. Of 34 patients evaluable for response to neoadjuvant chemotherapy, nine had a CR, 21 a partial response (PR), two a minimal response (MR), and one patient each stable disease (SD) and no response (NR). Of 31 patients who received local therapy, 15 were treated with surgery and radiotherapy and 16 with radiotherapy alone. Of 25 patients eligible to receive adjuvant chemotherapy only ten received all three intended cycles, while 15 received less or no adjuvant chemotherapy because of patient refusal, cumulative toxicity, or early disease progression. With a median follow-up time of 39 months, the median survival is estimated to be 20 months. Of eight patients with nasopharyngeal or paranasal sinus cancer, none has had disease recurrence. Patients with good initial performance status and low N-stage also had a significant survival advantage. Chemotherapy-related toxicities consisted mainly of mucositis, requiring 5-FU dose reduction in the majority of patients; similar toxicities were exacerbated in the adjuvant setting. The addition of methotrexate did not increase the CR rate over what has been reported for the combination of cisplatin and 5-FU alone. Certain subsets of patients appear to have a good prognosis when treated in this fashion. The administration of adequate adjuvant chemotherapy in patients with head and neck cancer remains difficult due to toxicity and poor patient compliance.

RESUMO

Hydroxyurea and fluorouracil (5-FU) are active cytotoxic drugs in head and neck cancer and have shown synergistic activity in vitro. Both drugs also act as radiosensitizers. Therefore, we administered radiotherapy at daily fractions of 180 to 200 cGy with simultaneous continuous infusion 5-FU at 800 mg/m2/d and escalating daily doses of hydroxyurea for five days. Cycles were repeated every other week until completion of radiotherapy. Thirty-nine inoperable patients were treated at six dose levels of hydroxyurea ranging from 500 mg to 3,000 mg orally daily. Little effect of hydroxyurea on the WBC or platelet count was noted in patients receiving less than 2,000 mg daily, whereas both parameters decreased progressively in patients receiving 2,000 mg daily or more. Mucositis occurred at all dose levels, requiring frequent dose reduction of 5-FU; however, in patients receiving a daily hydroxyurea dose of 2,000 mg or less, the median weekly 5-FU dose administered was 1,725 mg/m2 (86% of the intended 5-FU dose), whereas at daily hydroxyurea doses exceeding 2,000 mg, the median weekly 5-FU dose decreased to 1,133 mg/m2 (57%) (P = .001). Of 15 evaluable patients with recurrent disease after prior local therapy only one failed to respond; six had a complete response (CR), and eight a partial response (PR). Of 17 evaluable patients without prior local therapy, 12 had a CR, with no patient developing recurrence in the irradiated field to date; five patients had a PR. We conclude that the recommended dose of hydroxyurea in this regimen is 2,000 mg daily. That dose will cause mild to moderate myelosuppression and will allow for delivery of greater than 80% of the intended 5-FU dose. The activity of this regimen in poor-prognosis head and neck cancer exceeds 90%; its further investigation in previously untreated patients is warranted.

RESUMO

This study was performed to evaluate the free gastroomental flap for the reconstruction of mucosal and soft tissue defects after ablative surgery for head and neck cancer. Its use in a dog model was assessed in terms of the feasability of the surgical technique, acid secretion by the gastric mucosa, changes in the cell population of the graft, and the possibility that the omentum may augment lymphatic drainage after cervical node dissection. Gastroomental flaps were harvested, based on the gastroepiploic artery, and transplanted to the neck in ten dogs. Neck dissection and creation of a defect in the floor of the mouth were followed by microvascular anastamosis of the gastroepiploic vessels to suitable recipient vessels in the neck. Following this, the flap was sutured into place, reconstructing the defect in the floor of the mouth. The omentum was draped over the carotid artery and into the upper mediastinum. Intraoral pH remained stable during a 6-month follow-up period and there was no stomatitis noted. Radionuclide images suggested that the omental lymphatics contributed to regional lymphatic drainage. Histologic examination following sacrifice at 6 months showed atrophy of gastric glands but no epithelial metaplasia. We conclude that the free gastroomental flap is feasible, provides immediate restoration of soft tissue bulk, supplies a mucosal surface that adapts to the oral environment, and may augment regional lymphatic drainage.
