Superficial thrombophlebitis of the thoracoepigastric veins (also known as Mondor's disease) is an uncommon disorder that typically affects middle-aged women and classically involves the chest wall including the breasts. Only one previously published, non-operative case of the disease, describes how the condition can resemble a strangulated Spigelian hernia. Herein we describe another similar case in which the diagnosis was made intra-operatively. The extremely unusual and similar clinical findings we observed demonstrate that Mondor's disease can occur in the Spigelian hernia belt and cause diagnostic confusion.

BACKGROUND: The combination of cisplatin and 5-fluorouracil (5-FU) is considered standard therapy for patients with recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN). Paclitaxel has exhibited single-agent activity in patients with this disease. The authors conducted this study to evaluate the feasibility and efficacy of combining paclitaxel with cisplatin and 5-FU for patients with advanced or recurrent SCCHN. METHODS: Patients with recurrent, metastatic, or locally advanced SCCHN who had measurable or evaluable disease and no prior chemotherapy were eligible. The starting dose level consisted of paclitaxel 135 mg/m(2) on Day 1, cisplatin 75 mg/m(2) on Day 2, and 5-FU 1 gm/m(2)/day on Days 2-6. Due to Grade 4 mucositis, dose level 1 of 5-FU was reduced to 800 mg/m(2)/day on Days 2-6 (for 7 patients), and subsequently the 5-FU dose was adjusted to 1 gm/m(2)/day on Days 2-5 (for 17 patients). RESULTS: Twenty-five patients were enrolled, with a median age of 60 years and a median Southwest Oncology Group performance status of 1. Of the 25 patients, 16 had recurrent disease, 3 had metastatic disease at diagnosis, and 6 had untreated locally advanced SCCHN. Ninety-nine courses of therapy were administered, with a median of 5 courses. Major toxicities were neutropenia and mucositis. Significant neurotoxicity or nephrotoxicity were not observed. There were two treatment-related deaths (one each due to mucositis and neutropenic pneumonia), and these precluded further dose escalation. Fifteen of the 25 patients (60%) achieved a major response. Of significance is the response rate of 58% (11 of 19 patients) in those with recurrent or metastatic disease who had a duration of response ranging from 3 to 19+ months. Two of these 19 patients continue to be in remission of 19+ and 15+ months' duration, respectively. The median survival for patients with recurrent or metastatic disease was 6 months (range, 1-26 months), with a 1-year survival rate of 37%. CONCLUSIONS: The dose and schedule for the combination of paclitaxel, 5-FU, and cisplatin as determined in this study are feasible, with encouraging outcomes and activity in patients with recurrent or metastatic SCCHN. The results of this trial warrant larger-scale evaluation to determine the role of this combination in the management of patients with this disease.

In this study we have assessed zinc status and zinc-dependent cell-mediated immune functions (interleukin-2 production by mononuclear cells, natural killer cell lytic activity, and interleukin-1 beta production by mononuclear cells) in adult patients with squamous cell carcinoma of the upper aerodigestive tract at diagnosis and before any therapy was instituted. Inasmuch as significant interactions between zinc, copper, and iron exist, we also assayed the plasma copper level, serum iron level, and total iron-binding capacity in our patients. We recruited 30 cancer subjects and 21 control subjects. On the basis of cellular zinc criteria, we diagnosed a mild deficiency of zinc in 53% of cancer subjects. The plasma zinc level was not decreased in our subjects. A univariate analysis was applied by use of one-way analysis of variance comparing study variables among the three study groups (controls and zinc-deficient and zinc-sufficient cancer patients) and Tukey's multiple comparison test, and we showed that interleukin-2 production and natural killer lytic activity were decreased in zinc-deficient cancer patients. Interleukin-1 beta production (ELISA assay) was increased in both zinc-deficient and zinc-sufficient groups. Plasma copper level was not different, but the iron utilization was decreased in both groups of cancer subjects. We conclude that zinc deficiency and zinc-dependent immunologic dysfunctions are present in more than half of the patients with head and neck cancer in the Detroit area.

The combination of 5-fluorouracil (5-FU) and cisplatin is considered the most active chemotherapy for patients with recurrent squamous cell carcinoma of the head and neck (SCCHN), with an overall response rate of 30%. Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has demonstrated activity in SCCHN and synergy with cisplatin. To augment the activity of the combination of 5-FU and cisplatin, a pilot study was designed to determine the feasibility of combining 3-hour infusional paclitaxel with 5-FU and cisplatin. To be eligible, patients had to have recurrent or advanced SCCHN with measurable or evaluable disease and no prior chemotherapy. A minimum of three courses had to be delivered to determine cumulative toxicity. The starting dose level consisted of paclitaxel 135 mg/m2 on day 1, cisplatin 75 mg/m2 on day 2, and 5-FU 1 g/m2 on days 2 through 6. The first treated patient developed grade 4 mucositis, which resulted in reducing dose level 1 of 5-FU to 800 mg/m2/d on days 2 through 6 (seven patients); subsequently, the 5-FU dose was adjusted to 1 g/m2/d on days 2 through 5 (nine patients). To date, 17 patients have been enrolled, with a median age of 62 years (range, 48 to 75 years). Of the 17 patients, nine had recurrent disease following prior surgery and/or radiotherapy and eight had previously untreated advanced SCCHN. Major toxicities were neutropenia and mucositis. There were four early deaths (two treatment-related and two cancer-related). Forty-seven courses of therapy were delivered, with a median of two (range, one to five). The overall response rate in 14 response-evaluable patients was 71% (10 of 14 patients; eight partial and two complete responses). Five of seven response-evaluable patients with recurrent disease had major responses (one complete and four partial responses). At the current dose, the combination of paclitaxel/5-FU/cisplatin is feasible and shows very encouraging activity, particularly in patients with recurrent SCCHN.

There have been reports of a high incidence of hypopharyngeal stenosis in total laryngectomy patients when the surgery requires a partial pharyngectomy for pyriform sinus involvement. In this study, three groups were compared: total laryngectomy patients without partial pharyngectomy, total laryngectomy patients with partial pharyngectomy, and normal controls. All patients had received radiation therapy following surgery. All were maintaining oral nutrition, and none complained of dysphagia. Patients were tested between 1 and 7 months postradiation therapy, with a mean of 3 months. Measures of swallowing efficiency were based on scintigraphic data for a liquid swallow. Patients with partial pharyngectomy had abnormally long oropharyngeal transit times and low efficiency scores. For a subgroup of patients with partial pharyngectomy, swallowing data were available postsurgery and postradiation therapy. Postsurgery this patient group did not differ significantly from normal patients in swallowing efficiency, and swallowing efficiency deteriorated in postradiation therapy. This scintigraphic methodology is shown to be a sensitive method of assessing swallowing function in this patient population.

Gangrenous cholecystitis is an advanced form of acute cholecystitis associated with increased morbidity and mortality. We sought to determine the incidence of gangrenous cholecystitis in an urban VA hospital patient population and identify any distinguishing characteristics that may aid in its preoperative diagnosis. We retrospectively reviewed all urgent admissions that underwent cholecystectomy (n = 65) over the past 7 years at the Allen Park VAMC. Using histologic criteria, 17 (26%) of these patients had gangrenous cholecystitis. As a group compared to patients with nongangrenous cholecystitis, patients with gangrenous cholecystitis were statistically older (64 vs 54) and had an elevated WBC (15.4 vs 11.5) and increased serum glucose levels (203 vs 141). Preoperative imaging studies (ultrasound and cholescintigraphy) correctly identified only 31% of the gangrenous cholecystitis patients. We conclude that in an urban VA hospital patient population, the diagnosis of gangrenous cholecystitis cannot be accurately made or ruled out among urgent admissions with acute biliary disease. Considering the high incidence (26%) and difficulty confirming the diagnosis of gangrenous cholecystitis in this setting, we recommend early surgical intervention for this and similar patient populations.

The clinical records of 94 patients with regionally advanced melanoma (nodal disease or regional satellites) were reviewed to determine the value of preoperative bone and liver imaging. Of 68 bone scans obtained, none were suggestive of metastases. of 97 liver imaging studies (computed tomography, scintiscan, or sonography) in 88 patients, only two were found to have demonstrable metastases. Liver enzyme elevation was present in both of these patients. Bone and liver imaging in the absence of signs or symptoms of dissemination by history, physical examination, chest x-ray, and enzyme determination for regionally advanced melanoma appears to be of little value unless the patient is involved in a protocol study.
