[Early stages of laryngeal cancer (I-II stage) and therapeutic options: case report and review of literature].

Between 1987 and 1993, 36 patients with early squamous cell carcinoma of the larynx (I-II stage) were treated with radiotherapy, at the National Institute for Cancer Research of Genoa; 25 patients were stage I (5 T1N0 of supraglottic larynx, 15 T1aN0 and 5 T1bN0 of glottic larynx) and 11 patients stage II (7 T2N0 of supraglottic larynx and 4 T2N0 of glottic larynx); there were 32 males (89%) and 4 females (11%), ages ranging from 34 to 83 years (mean age 61 years). The radiotherapy was performed utilizing the X-ray of a 6 MV linear accelerator, with a daily conventional fractionation and a dose of 66-70 Gy/33-35 fr./7 weeks, with co-axial latero-lateral beams including cervical lymph-nodes, except for T1N0 glottic cancer. The median follow-up was 51 months (range 8-84 months). The local control rate of all the patients was 80.5% at 51 months. According to the stage and tumor subsite, it was 80% for stage I a-b of the glottic site, 60% for the stage I of supraglottic site, 91% for stage II of supraglottic and glottic site. Only 6 patients (18%) underwent the salvage surgery and in all the patients the illness was under control. The overall survival rate was 83.3% at 51 months (4 patients died of a second tumor (11%) and 2 from heart disease (5.5%)). The only complication we observed was a glottic edema. The analysis of our results demonstrates that radiotherapy seems to be more appropriate in the T1a-b glottic cancer. These results are in agreement with those obtained by other studies. On the contrary, the results obtained with radiotherapy, in the T2N0 glottic cancer, are not satisfactory, with regard to local control, as those obtained with surgery, but offers best functional results. In most T2N0 tumors, after the failure of radiotherapy, a reconstructive laryngectomy is still possible. We also obtained good results with the supraglottic lesions. The small number of cases we treated does not allow us to achieve final conclusions and other studies are necessary to confirm our results.

Pre-operative localization of non-palpable lesions in breast cancer by charcoal suspension.

The use of preoperative localization procedures for non-palpable breast lesions (NPBL) is becoming more and more widespread, increasing the detection of early breast cancers. From October 1987 to July 1992, at our Institution, 253 patients (pts) with clinically non-palpable lesions underwent surgical treatment. Of the 253 pts, the lesions have been localized in 95 cases by a needle system, and in the other 158 cases by a dye injection of a 3% sterile charcoal suspension using stereotactic method (118 cases) or sonography (40 cases). The patients' mean age was 53 years (range 30-75). Mammography revealed regular opacities in 133 cases, clustered microcalcification in 75, diffuse microcalcification in 24, opacities with irregular borders in nine and opacities with internal microcalcifications in 12. The histological findings showed benign breast disease in 175 cases (69.2%), borderline breast disease in 23 (9.1%) and malignancy in 55 (21.7%). The benign/malignant/borderline lesions ratio was 3.2:1. The majority (70%) of these malignant lesions were small cancers (less than 1 cm in diameter) and without lymph-node involvement. The biopsy cost (benign/malignant/borderline ratio, patients discomfort and cosmetic result) has been acceptable.

Temporary regression of recurrent squamous cell carcinoma of the head and neck is achieved with a low but not with a high dose of recombinant interleukin 2 injected perilymphatically.

The efficacy of ten daily injections of 500 or 500,000 U of recombinant interleukin 2 (IL-2) day-1 given 1.5 cm from the insertion of the sternocleidomastoid muscle on the mastoid was evaluated in 31 patients with recurrent head and neck squamous cell carcinoma. No toxic effects were noted. One complete response (CR) and three partial responses (PRs) were observed in the 16 patients who received 500 U of IL-2, whereas the higher dose was not effective. The CR was recorded in one of the seven patients with a oropharyngeal recurrence. Partial responses were obtained in 1/5 patients with hypopharyngeal recurrences, in 1/5 patients with oral cavity recurrences and 1/7 patients with laryngeal recurrences. The duration of the responses was 3-5 months and additional courses of ten injections of IL-2 had no further effect.

Role of B72.3 iodine 125-labeled monoclonal antibody in colorectal cancer detection by radioimmunoguided surgery.

BACKGROUND: Radioimmunoguided surgery (RIGS) by means of radiolabeled monoclonal antibodies and a probe has been reported to be useful in recognizing subclinical tumor deposits during operation. Aim of this study was to understand the limits of this technique and to assess the potential diagnostic use of RIGS in colorectal cancer surgery. METHODS: Monoclonal antibody B72.3 reacting with TAG 72 antigen, labeled with iodine 125, was injected in 32 patients with primary tumors and in 22 patients with recurrent colorectal cancer. One hundred thirty-three suspected tumor sites were evaluated during operation by means of probe and resected with immunohistochemistry as control. RESULTS: Primary tumor sites were localized by RIGS in 60% of cases, and recurrent sites were localized in 82% of cases. There was a significant correlation both for primary (p < 0.001) and recurrent (p < 0.001) tumor sites between intraoperative RIGS findings and TAG 72 tumor antigen expression. Results obtained with the probe were instrumental in modifying the surgical approach in six (27%) of 22 patients with recurrences, allowing the removal of tumor masses that would otherwise have been overlooked. CONCLUSIONS: The results of RIGS seems to be encouraging in terms of clinical use. The potential high diagnostic resolution appears to improve surgical ablation of colorectal cancer, especially in patients with recurrent cancer or suspected recurrent tumors who have negative results for intraabdominal disease by all other roentgenographic criteria with rising carcinoembryonic antigen or TAG 72 antigen levels.

Treatment of advanced squamous-cell carcinoma of the head and neck with alternating chemotherapy and radiotherapy.

BACKGROUND: For patients with advanced, unresectable squamous-cell carcinoma of the head and neck, radiotherapy is the standard treatment but has poor results. We therefore designed a randomized trial to determine whether alternating chemotherapy with radiotherapy would improve the survival of such patients. METHODS: Patients in the trial had biopsy-confirmed unresectable, previously untreated Stage III or IV, squamous-cell carcinoma of the oral cavity, pharynx, or larynx. They were randomly assigned to chemotherapy consisting of four cycles of intravenous cisplatin (20 mg per square meter of body-surface area per day for five consecutive days) and fluorouracil (200 mg per square meter per day for five consecutive days) alternating with radiotherapy in three two-week courses (20 Gy per course; 2 Gy per day, five days per week), or to radiotherapy alone (up to 70 Gy; 2 Gy per day, five days per week). RESULTS: The 80 patients given chemotherapy alternating with radiotherapy and the 77 given radiotherapy alone were comparable in terms of age, sex, performance status, disease stage, and site of the primary tumor. Complete responses were obtained in 42 percent of the patients in the combined-therapy group and 22 percent of those in the radiotherapy group (P = 0.037). The median survival was 16.5 months in the combined-therapy group and 11.7 months in the radiotherapy group (P less than 0.05); the 3-year survival was 41 percent and 23 percent, respectively. Severe mucositis occurred in 19 percent of the patients in the combined-therapy group and 18 percent of those in the radiotherapy group. CONCLUSIONS: In patients with advanced unresectable squamous-cell carcinoma of the head and neck, chemotherapy alternating with radiotherapy increases the median survival and doubles the probability of survival for three years as compared with radiotherapy alone. However, since local disease cannot be controlled in over half the patients who receive the combined treatment and since almost two thirds die within three years, further improvements in management are necessary.

Perilymphatic injections of recombinant interleukin-2 (rIL-2) partially correct the immunologic defects in patients with advanced head and neck squamous cell carcinoma.

Patients with advanced head and neck squamous cell carcinoma (HNSCC) are severely immunocompromised. In virtually all such patients who have been studied, reduced numbers of circulating CD3+ T-cell-receptor (TCR)alpha/beta+ T lymphocytes, a reduction of natural killer (NK) activity, and a poor induction of lymphokine-activated killer (LAK) cell activity (following in vitro treatment with recombinant interleukin-2 [rIL-2]) have been detected. Recently, however, it has been demonstrated that perilymphatic injections of low doses of rIL-2 may induce a local reduction of tumor masses in these patients. The present study, a cooperative pilot effort on the clinical effects of this route of administration, showed an activation of the lytic machinery in lymphocytes belonging to the T-cell lineage, as well as a potentiation of NK activity in the peripheral blood. These findings demonstrated that the severe immunodeficiency of HNSCC patients may be at least partially corrected by in vivo administration of rIL-2.

[The diagnosis and therapy of recurrent tumor of the rectum].

The authors review the pathogenesis of locoregional recurrences of rectal cancer, pointing out clues for the diagnosis and staging of the disease which are valuable for the definition of a treatment strategy. Surgery is the mainstay of any attempt to cure those recurrences that are amenable to radical resection; over and above the diagnostic role of second-look laparotomy in suspected cases, surgery must include those measures able to reduce actinic damage whenever postoperative radiotherapy is required. On the other hand, palliative surgery is necessary to resolve the presence of intestinal obstruction, fistulous tract, or the removal of abscess and necrotic tissue. In these cases, the quality of life seems to be the prime factor in the choice of therapy (radiotherapy, loco-regional or systemic chemotherapy, hyperthermia).

[Neoplasms of the major and minor salivary glands. The diagnostic and therapeutic approaches and case presentations].

Between January 1982 and December 1988, 37 patients with neoplasm of salivary glands have been treated in our Division of Surgical Oncology. The sites of tumors were: parotid 26, submandibular gland 4, minor salivary gland 7. The preoperative diagnostic procedures were: sialogram, ultrasonogram, fine needle aspiration. Malignant tumors were 16:5 adenoca., 4 metastases, 3 adenoid cystic, 2 mucoepidermoid, 1 acinic cells, 1 lymphoma. Twenty-one patients affected by neoplasms and 5 by malignant tumors were treated with surgery only. Nine patients affected by malignant tumors were treated with surgery and RT. Two patients were treated with RT only. The first therapeutic step is surgery; in order to control local evolution of tumor, postoperative irradiation is recommended. Possible indications of preoperative diagnostic procedures and the therapeutic choices are discussed.

A phase I study of recombinant interleukin-2 intraperitoneal infusion in patients with neoplastic ascites: toxic effects and immunologic results.

A phase I study to evaluate the use of i.p. infusion of recombinant interleukin-2 (rIL-2) was planned. The following dose levels were calculated: 0.1, 0.3, 1.0, 3.0 and 10 mg/m2/day for 14 days, but only the second levels were reached. In this trial the acute toxic effects at this dosage included cardiac ischemia, transient liver impairment and septic peritonitis. The maximum tolerated dose (MTD) was 0.3 mg/m2/day for 14 days. In addition, two patients developed peritoneal fibrosis. No objective responses were observed. Therefore, in order to explore the biological activity of low (nontoxic) doses, three patients (one untreated and two previously treated with rIL-2) were infused with 0.01 and 0.03 mg/m2/day for 7 days. Potentiation of cytolytic activities in peritoneal lymphocytes and activation of a lymphokine cascade in the ascitic fluid were observed at doses ranging from 0.03 mg/m2/day to 0.3 mg/m2/day. These findings in association with the toxic effects observed at the MTD suggest the use of the minimum effective dose for future locoregional immunotherapeutic protocols.

[Anatomo-functional consequences of the radical surgery of the cervico-cephalic region in oncologic patients].

The role of surgery in head and neck cancer treatment is now well established, as it appears the most effective approach to such patients, while other therapies (i.e. chemotherapy, radiotherapy) can be of some help as second choice procedures. Surgery demonstrates however its own pitfalls, as it can often cause secondary anatomo-functional defects. The main problems appear to be related to the impossibility of physiological feeding following composite resection for oral cancer. An immediate reconstruction by transposition of myocutaneous flaps is of the utmost importance, as it reestablishes the preoperative condition lessening hospitalization time and postoperative disabilities. Neurological lesions, an unfrequent major complication of cervical lymphadenectomy, can cover a wide range of seriousness, from hardly detectable sensorial deficits to the impossibility of spontaneous ventilation. In this paper the Authors, on the basis of their experience, describe the measures to be taken in order to avoid secondary lesions (or to minimize their effects) in head and neck cancer surgery.

Role of diagnostic lymphnode biopsies in 56 anti-HIV positive patients.

The authors have examined two separate series of samples from 33 and 23 anti-HIV positive patients with persistent generalized lymphadenopathy (PGL) undergoing lymphnode biopsy. For the first group of patients, the aim was to evaluate the diagnostic and prognostic correlation between clinical and laboratory features and histologic findings. For the second group, an assessment was made of the indications for lymphnode biopsy as determined by the rate of positive histopathologic findings. Histologic alterations were classified into four types according to Ràcz, without knowledge of clinical and laboratory data. At the time of biopsy, the first sample (n = 33) included 21 lymphadenopathy associated syndrome (LAS) (64%), 6 ARC (18%), and 6 AIDS (18%) patients; a significant prevalence of type 1 histologic features was evident in LAS/ARC patients, while type 4 was exclusively present in the AIDS group. These preliminary results suggested that only symptomatic anti-HIV positive patients (ARC/AIDS) should have been selected for lymphnode biopsy, because of the expected high rate of opportunistic infections, malignant lymphoma, or Kaposi's sarcoma (KS) in this specific subset of patients. Actually, in the second sample of 23 patients (ARC = 8: AIDS = 15) the detection rate of AIDS-related neoplasms included ten Kaposi's sarcoma and three Hodgkin's disease. These findings suggest that diagnostic lymphnode biopsies should be limited to selected anti-HIV positive patients with evidence of AIDS-related neoplasms or treatable opportunistic infections, or for the purpose of detecting histopathologic features of prognostic significance.

Phenotypic and functional characteristics of tumor-associated lymphocytes in patients with malignant ascites receiving intraperitoneal infusions of recombinant interleukin-2 (rIL-2).

In the course of a phase I trial, in which recombinant IL-2 (rIL-2) was infused intraperitoneally (i.p.) in patients with peritoneal carcinomatosis, we evaluated the effect on "tumor-associated lymphocytes" (TAL) isolated from the ascitic fluid. No major changes in the percentages of cells expressing the CD3, CD4, CD8, Leu-7, OKM1 and WT-31 antigens were detected either in TAL or in peripheral blood lymphocytes (PBL) after 7 days of rIL-2 infusion. In contrast the percentages of TAL (but not PBL) expressing surface IL-2 receptor (Tac), or LAK-1 antigen were sharply increased. Analysis of cytolytic functions showed a potentiation of the lytic activity against natural-killer (NK) sensitive K562 target cells and the de novo appearance of lytic activity against fresh melanoma cells. In one patient IFN-gamma was detected in the ascitic fluid following rIL-2 infusion. T-cell clones derived from the patient were analyzed for the IFN-gamma production. While only approximately 40% of PB-derived control clones produced medium to low amounts of IFN-gamma, all of the TAL-derived clones produced medium to high amounts of the lymphokine.
