A 45-year-old female patient with a neurofibroma of the hypopharynx is reported. She had complained of swallowing discomfort for 3 months. Indirect laryngoscopy showed an oval tumor with a smooth surface in the posterior wall of the hypopharynx. Xeroradiography was effective for defining the tumor. Removal of the tumor was performed by an infrahyoid horizontal pharyngotomy under general anesthesia. The tumor had an indistinct capsule. The nerve from which the tumor originated was not clear. Histologically, the tumor was diagnosed as neurofibroma. The patient had no other neurogenic tumor and has been well without recurrence after the surgery.

This three-year project evaluates the biopsychosocial effects of interleukin-2 (IL-2) therapy on the first 45 patients treated with the therapy at the Moses Division of the Montefiore Medical Center in Bronx, NY, starting in April 1986. Therapy with IL-2 and lymphokine-activated killer (LAK) cells is a promising new development but requires an extensive amount of supportive care. Various important issues must be considered in planning the care of patients being treated with IL-2, including the effects of the treatment on quality of life, the cost of resources necessary for providing therapy, and the emotional effects of treatments. The instruments used to measure the various aspects of quality of life were the Sickness Impact Profile, the Inventory of Current Concerns, the Symptom Distress Scale, the Acute Physiology and Chronic Health Evaluation Scale, and the Therapeutic Intervention Scoring System. The researchers believe that, in addition to tumor response, the biopsychosocial and financial effects of treatment should be understood.

This is the first report of a fully documented case of an ossified mucin-producing benign choroid plexus tumor. This was a chance finding in a man who complained only of posttraumatic low back discomfort. The ossification of the tumor appears to have been therapeutic. Mucin production may be a defense mechanism.

The authors describe their experience with the extended Hartmann procedure as the elective and definitive operation in a selected group of 36 patients having primary adenocarcinoma of the rectum. The operations were carried out between 1st January 1978 and 31st December 1989. The average age of the patients was 70 years (range 37 to 84 years). Ten patients had preoperative radiotherapy because of deep infiltration and (or) fixation of the tumor. In this series the Hartmann procedure was chosen because abdomino-perineal excision was not needed and low anterior resection could not warrant acceptable continence. With a Hartmann procedure the risks of a low colorectal or colo-anal anastomosis were avoided while the perineal excision was abandoned. Eight patients had hepatic metastases. The Dukes' classification of the remaining patients was A in two, B in nine and C in 17 patients. Postoperative morbidity was within acceptable limits for this particular patient group. There was no hospital mortality. Twenty patients had a potentially curative resection prior to 31st December 1987, thus making them available for follow-up of at least 2 years. Ten of these patients have been in follow-up without evidence of disease for an average of 76 months (mean 65 months, range 28-123 months). The authors conclude that the procedure is safe and that the remaining rectal stump does not generate morbidity or discomfort. Considering the fact that only two of the 36 patients had a Dukes' A tumor, the low recurrence rate shows that the Hartmann procedure yields satisfactory pelvic radicality.

Our preliminary data indicate that the formation of micronuclei (MN) in treated tumor cells is a predictive variable for tumor response to treatment. In a pilot study involving four patients who received both radiation therapy and hyperthermia, fine needle aspirate (FNA) samples were taken and analyzed before therapy, and after each 1000 centigray (cGy) up to 3000 cGy. The results indicate a correlation between increasing formation of micronuclei and decreasing tumor volume. All of the patients in this Study have had their tumors under control for at least one year. Our preliminary data demonstrated that a high level of micronuclei in tumor cells correlates with favorable response of the tumor to treatment with radiation and heat. The assay is easy to perform and FNA biopsy could be done in the clinic with minimal discomfort to the patient.

This is a report of a Phase I/II study activated in March 1984 and completed in October 1988 by the Radiation Therapy Oncology Group on the feasibility/toxicity of hyperthermia in patients with deep-seated malignant tumors. The main objective of this study was to evaluate the morbidity of regional hyperthermia (systemic and regional, acute and late effects); a secondary objective was to evaluate tumor response to combined irradiation and regional hyperthermia. A total of 54 patients with locally advanced abdominal or pelvic malignancy were accrued to this study; 42% were male and 58% female. Seventy-five of the patients had pelvic tumors and 25% abdominal tumors. Acute toxicities included grade 4 in three patients (1 cutaneous, 1 infection and 1 chemical peritonitis) one grade 3 (skin), and 12 grade 2 toxicities (6 skin and 6 gastrointestinal). With regard to late toxicities, grade 4 was noted in one patient (skin), grade 3 (GI) in one, and grade 2 (skin, peripheral neuropathy) in six patients. The prescribed course of hyperthermia was completed in 17 (32%) of patients. In 36 patients (68%) the course of hyperthermia was terminated, primarily because of patient discomfort. Tumor response was assessed by physical examination or radiological studies. Of 44 patients evaluable for response, there were 17 (39%) complete responses and 6 (14%) partial responders. Significant technical problems in heat delivery and thermometry remain.

Ultrasonic surgical aspiration is a useful technique for safe and accurate tissue removal. This study was conducted to evaluate its role in noninvasive vulvar disease. From December 1988 to March 1990, 27 patients underwent ultrasonic surgery; nine patients had vulvar intraepithelial neoplasia (VIN) and 18 had condylomata acuminata. All surgical procedures were done under general anesthesia, with two patients requiring hospitalization for perineal care and pain control after extensive vulvar surgery. Recurrent or persistent disease occurred in four patients with condylomata acuminata and in two with VIN, with a mean follow-up of 50 weeks. Reepithelialization was completed within 5 weeks and no patients developed vulvar scarring. Adequate samples for histopathologic review were obtained in 26 patients. Identical histologic grading occurred in all 13 patients who had preoperative vulvar biopsies and an adequate aspiration specimen. Ultrasonic surgery permits precise and rapid removal of epithelial lesions with rapid healing, minimal patient discomfort, excellent cosmetic results, and histopathologic documentation.

To determine the presence of chest wall and mediastinal invasion by lung cancer and to establish the origin of chest tumors, we studied 12 patients with intrathoracic tumors by using chest CT combined with artificial pneumothorax. Six patients had primary lung cancer, two had metastases, and one each had neurofibroma, pericardial cyst, chondroma of the rib, and malignant mesothelioma. All 12 tumors abutted the chest wall or mediastinum and could not be separated by conventional CT. Between 400 and 800 ml of air was injected into the pleural space before a second CT scan was obtained. No invasion was found at surgery in cancers that were separated from chest wall or mediastinum on CT scans. Surgery revealed chest wall invasion in three patients in whom the CT scans showed that the tumor was not separated from the chest wall. Only one patient with a tumor that was not separated from the mediastinum on CT did not have mediastinal invasion: in this case, only adhesions were found at surgery. Thus, in the eight patients with primary lung cancer and metastasis, sensitivity, specificity, and accuracy were 100%, 80%, and 88%, respectively. In four patients with mediastinal or pleural tumor, CT combined with pneumothorax was useful for establishing the origin of tumors. In all, 11 of the 12 patients were correctly evaluated by using this method. No complications occurred, except for mild chest discomfort in one patient. This study suggests that chest CT combined with artificial pneumothorax is useful for the evaluation of the extension of lung cancer into the chest wall and mediastinum and for the diagnosis of the site of origin of intrathoracic tumors.

Regional hyperthermia in deep-seated tumors can be limited by excessive heating of normal tissues, usually associated with pain or local discomfort. In this report, 57 hyperthermia treatments in 8 patients with locally advanced presacral recurrences of colorectal cancer were analyzed with respect to normal tissue temperatures, especially with respect to the perineal fat temperature. In 27 treatments, 1 to 2 catheters had been inserted from the perineal region through a large part of the perirectal and presacral fat into the tumor, so that temperature profiles of the perineal fat could be obtained. The mean maximum temperature (+/- SD) of the vagina, rectum, bladder, muscle tissue, and perineal fat was 40.8 +/- 1.2 degrees C, 40.9 +/- 1.6 degrees C, 40.5 +/- 1.6 degrees C, 39.8 +/- 0.7 degrees C, and 42.6 +/- 1.1 degrees C, respectively. The mean maximum systemic temperature (+/- SD) was 37.7 +/- 0.7 degrees C. In 42% of the treatments, the temperature in the perineal fat ranged between 43 and 46 degrees C and was treatment-limiting. In conclusion, overheating of the perineal fat is a problem in the treatment of eccentrically located tumors of the presacral region when relatively high temperatures in the tumor will be maintained for longer time periods.

The purpose of this prospective clinical trial was to determine the reliability of the Pipelle endometrial biopsy instrument in recovering adequate tissue for confirmation of the diagnosis of endometrial cancer in patients with known endometrial carcinoma, and to compare endometrial histology of the sampling specimen with that of the subsequent hysterectomy specimen. Forty patients were enrolled in this study. All biopsies were performed in the office without anesthesia. The patients had a median age of 62 years (range 40-83). Discomfort was reported by the patient as mild, moderate, or severe; only two patients (5.0%) reported severe pain. There were no complications experienced with endometrial sampling. Thirty-nine of 40 specimens (97.5%) confirmed endometrial carcinoma; therefore, this study yielded a 97.5% sensitivity for the Pipelle endometrial sampling device. Comparing Pipelle and hysterectomy histology for individual patients, the histologic grade was the same in 29 (74.4%), while the Pipelle demonstrated a more advanced degree of differentiation in five (12.8%) and a lesser degree in five (12.8%). There was no residual tumor identified in one hysterectomy specimen (2.5%). Among the 12 patients who had a D&C for diagnostic purposes before referral, the Pipelle biopsy correlated with the D&C histology in ten of 12 (83.3%) and revealed a more advanced grade of tumor in one (8.3%) and a more differentiated grade in one (8.3%). In one patient, the D&C histology was adenocarcinoma grade 1, with the Pipelle demonstrating atypical hyperplasia and the hysterectomy specimen interpreted as endometrial adenocarcinoma in situ. This study demonstrates the Pipelle to be an accurate device for endometrial sampling in patients with endometrial carcinoma.
