Neo-adjuvant organ-preserving chemotherapy in the management of locally advanced oral cavity and oropharynx cancer.

We designed an open, non-randomized clinical study to assess as the first endpoint the feasibility of sparing surgery and of preserving organ/function by using neo-adjuvant chemotherapy (NAG) in oral cavity and oropharynx cancer patients, and, as the second endpoint, the clinical response to this treatment approach and its duration. Moreover, an attempt was made to scale the extent of surgery by means of an Arbitrary Scale assigning different percentages to the different extents of surgical resection. Twenty-five patients with primary oral cavity and oropharynx cancer (stage III-TV) were enrolled in the study and were assigned to either the classical Al-Sarrafs regimen (1) (n=15) or to a regimen (2) consisting of cisplatin 80 mg/m(2) i.v. on day 1, 5-FU 600 mg/m(2) on days 2-5 and vinorelbine 20 mg/m(2) on days 2 and 8 (n=10). The 25 patients were all evaluable for response to NAC and 20 of them were evaluable for organ preservation. The overall response (OR) rate was 86.6% (13/15 patients) for regimen 1 (cisplatin + 5-FU) and 80% (8/10 patients) for regimen 2 (cisplatin + 5-FU + vinorelbine). The median follow-up duration was 20.6 months. 5/20 (25%) patients completely avoided surgery, 5/20 (25%) patients had a reduced extent of surgical resection, while: 10/20 (50%) patients received the previously planned surgical resection. Altogether, 10/20 (50%) patients treated with NAC either avoided or achieved a reduction in the previously planned surgical resection. Moreover, organ function was evaluated to support the assessment of treatment outcome in our patients. For this purpose we selected the Performance Status Scale for Head and Neck Cancer Patients: as expected, no significant impairment was detected in the area of comprehensibility of speech, but we were rather surprised that no significant impairment was found in the two areas of eating in public and normalcy of diet. NAG-associated toxicity was moderate and similar in the two chemotherapy regimens. The most relevant contributions offered by our study are represented by i) a Scale aimed at measuring as precisely as possible the reduction of surgical resection made possible by NAC compared to surgery planned before NAC and ii) an attempt to support the results with an assessment of treatment outcome.

Neo-adjuvant (primary) organ-preserving chemotherapy in the management of locally advanced laryngeal carcinoma.

We designed an open, non-randomized, phase II clinical study to assess as the first endpoint the feasibility of sparing surgery and of preserving organ/function by using neoadjuvant chemotherapy (NAC) laryngeal cancer patients, and, as the second endpoint, the clinical response to this treatment approach and its duration. 32 patients with primary laryngeal cancer (stage III-IV) were enrolled in the study and were assigned to either the classical Al-Sarrafs regimen (20 patients) or to a regimen consisting of cisplatin 80 mg/m(2) i.v. on day 1, 5-FU 600 mg/m(2) on days 2-5 and vinorelbine 20 mg/m(2) on days 2 and 8 (12 patients). The patients were divided into 2 groups: A) those requiring total laryngectomy (TL) and B) those not requiring TL, i.e. patients eligible for conservative for conservative surgery. The 32 patients were all evaluable for response to NAC and 31 were evaluable for The complete remission rate was 50% (16/32) and the partial remission rate was 46.9% (15/32) with an overall response rate of 96.9%. The median follow-up duration was 20.2 months. Overall, 23 patients required TL (group A) and 8 patients a conservative laryngectomy (group B). 7/23 (30.5%) patients of group A did not undergo surgery (score 4) and 6/23 (26%) achieved a partial larynx preservation (3/23 score 3, 1/23 score 2, 2/23 score 1), while 10/23 (43.5%) received the previously planned TL (score 0). 5/8 (62.5%) patients of group B did not undergo surgery, whereas 3/8 (37.5%) received the previously planned surgery (score 0). Therefore, 12/31 patients (38.7%) completely avoided surgery and 6/31 (19.4%) achieved a reduction in the extent of planned surgical resection, that is 18/31 patients (58.1%) achieved a reduction in the extent of previously planned surgery attributable to NAG. Moreover, 3/31 patients underwent the previously planned conservative surgery consisting of H-SGL/HG. Altogether 21/31 (67.7%) patients preserved function. The most relevant contributions offered by our study are represented by i) a scale aimed at measuring as precisely as possible the reduction of surgical resection made possible by NAC compared to surgery planned before NAC and ii) by an attempt to support the results with an assessment of patients treatment outcome. Although the scale provided by us is an arbitrary one, it must be emphasized that our goal was to address the issue of quality of life in cancer patients by a more precise quantification of organ/function preservation.

Clinical and immunological evaluation of schizophyllan (SPG) in combination with standard chemotherapy in patients with head and neck squamous cell carcinoma.

A phase II randomized controlled trial was carried out to evaluate the clinical efficacy and tolerability of Schizophyllan (SPG) used in combination with standard chemotherapy in the neoadjuvant setting in patients with locally advanced head and neck squamous cell carcinoma. Several immunological parameters were considered to assess the immunoregulatory activity of SPG in the: same patients. The clinical and immunological evaluations were performed both before and at the end of the study (4 months later). All patients received standard chemotherapy for head and neck squamous cell carcinoma according to one of the following treatment regimens: 1) cisplatin 100 mg/m(2) i.v, day 1, 5-FU 1,000 mg/m(2) i.v. continuous infusion days 1 to 5; 2) cisplatin 80 mg/m(2) i.v, day 1, 5-FU 600 mg/m(2) i.v. over 4 h days 2 to 5, vinorelbine 20 mg/m(2) i.v. days 2 and 8. Antineoplastic regimens were repeated every 28 days x 4 cycles for approximately 4 months. SPG was administered weekly at a single dose of 40 mg intramuscularly for 4 months in addition to standard chemotherapy. Twenty-six patients were enrolled in the study, 22 of whom were evaluable. Thirteen patients were assigned to Arm A (treatment with SPG associated with chemotherapy, regimen 1 or 2) and 9 patients to Arm B (treatment with chemotherapy, regimen 1 or 2, alone). The overall response rate was not significantly different between the two Arms (92.3% in Arm A vs. 100% in Arm B), although a higher number of complete responses (CR) (3 = 23.1%) was registered in Arm A. Overall, the SPG treatment does not seem to have induced significant changes of the immunological parameters of our patients: this may be due to both the advanced cancer stage and the effect of chemotherapy, which are both well known causes of immunodepression. The significant differences between the two Arms were only: the CD8(+) lymphocytes were decreased in the patients treated with SPG and increased in controls; serum levels of IL-1 alpha was lower in patients treated with SPG than in the control group; the production in culture of IL-1 alpha was higher in Arm A than in Arm B and IL-6 was higher in Arm B than in Arm A. Treatment with SPG was proven safe and was well-toleratedby all patients.

Comparison of oral 5-HT3-receptor antagonists and low-dose oral metoclopramide plus i.m. dexamethasone for the prevention of delayed emesis in head and neck cancer patients receiving high-dose cisplatin.

A phase III, single-institution, open, prospective, randomized, parallel study was carried out on head and neck cancer patients to compare a combination of low-dose (20 mg q.i.d.) oral metoclopramide (M) + i.m. Dexamethasone (D) with an oral 5-HT3-Receptor Antagonist (5-HT3-RA) alone in the prevention of high-dose (HD > or = 80 mg/m2) cisplatin-induced delayed emesis. 51 consecutive patients, all but two with advanced stage of disease, were treated for a total of 198 chemotherapic cycles: 23 patients entered Group A (5-HT3-RA) receiving a total of 108 cycles, 28 patients entered Group B (M + D) receiving a total of 90 cycles. The treatment groups were well matched for age, sex (almost all patients were males), ECOG PSR, stage of disease and alcohol intake. The efficacy of M + D was significantly higher than that of 5-HT3-RA in achieving complete protection (CR 88.9% vs 72.2%, chi2 9.9, p = 0.002) and major efficacy (ME: CR + MR) (94.5% vs 85.2%, chi2 5.6, p = 0.02). Generally, for both treatments (5-HT3-RA and M + D) a good control of delayed emesis was achieved in patients who had complete protection on acute emesis. A good control of acute emesis had a highly positive predictive value of delayed emesis for both treatments without significant difference between them (CR 85% for M + D and 82% for 5-HT3-RA; ME 88% for M + D and 92% for 5-HT3-RA). The failure (F) on acute emesis had a significantly higher negative predictive value of delayed emesis for M + D (98%) than 5-HT3-RA (67%). Our study is, to our knowledge, the first comparing M + D vs one 5-HT3-RA alone in the prevention of HD cisplatin-induced delayed emesis in a properly designed clinical trial. Our results show that M + D are more effective than 5-HT3-RA alone in the prevention of HD cisplatin induced delayed emesis, whereas 5-HT3-RA may be the treatment of choice in patients who had acute vomiting. Our study demonstrated not only the persistence of antiemetic efficacy but also increasing efficacy, during subsequent courses. Our results confirm that protection from acute emesis plays a major role in the appearance and control of delayed emesis.

Chemo-immunotherapy for advanced-stage malignancies and its impact on quality of life: multidimensional evaluation in ten cancer patients.

The aim of our study was to compare the impact of chemotherapy alone with that of chemotherapy plus immunotherapy on the quality of life (QL) of patients affected by advanced-stage malignancies (eight head and neck squamous-cell carcinomas, two melanomas). Ten patients receiving chemotherapy and immunotherapy sequentially were evaluated. The impact on QL was assessed by both objective and subjective scales. Evaluation was performed before the first cycle of therapy, at the end of chemotherapy, and after immunotherapy. The analysis of our data showed that the association of chemotherapy and immunotherapy did not significantly worsen the QL of patients as compared to chemotherapy alone.

Primary T cell CD30-positive anaplastic large-cell lymphoma associated with adult-onset celiac disease and presenting with skin lesions.

We report the case of a 52-year-old woman with primary CD30+ anaplastic large-cell lymphoma of T cell phenotype with skin involvement, stage IVB, fulfilling almost all the clinical, histopathologic and immunophenotypic criteria for this disease, associated with adult-onset celiac disease. The diagnoses of malignancy and celiac disease were made during the same clinical episode. The clinical course of the patient has been extremely favorable and she is in complete remission, 15 months after finishing consolidation therapy.

Evaluation by multidimensional instruments of health-related quality of life of elderly cancer patients undergoing three different "psychosocial" treatment approaches. A randomized clinical trial.

Our study belongs to the clinical trials in which the health-related quality of life (HQL) evaluation constitutes the primary endpoint. It was carried out with the aim of comparing the impact of three different types of psychological intervention, namely a psychopharmacological treatment alone, the same treatment plus social support carried out by volunteers (SSV) and a third treatment modality including "structured psychotherapy" (autogenous training), on improving the HQL of elderly cancer patients undergoing antineoplastic therapy with symptoms of anxiety and/or depression related to their disease. The eight questionnaires used for HQL evaluation were generally self-rated and multidimensional but unidimensional models were also employed. Seventy-four patients aged over 65 years with either solid tumors in different sites or hematological malignancies, generally in advanced stages (III-IV), were enrolled in the study. Of these patients, 72 (42 men and 30 women, mean age 70.68 years, range 66-85) were evaluable. Our study highlighted the usefulness of the pharmacological therapy (alprazolam + sulpiride) and of other specific ancillary treatments in reducing the incidence of the main HQL-related side-effects of antineoplastic therapy and the superiority of an "integrated" strategy, based both on psychopharmacology and psychosocial interventions, such as SSV with or without structured psychotherapy. The one-way analysis of variance carried out by us did not allow us to draw definitive conclusions about which of the two integrated treatments was to be considered the treatment of choice, as they proved to be almost equally effective.

Neo-adjuvant chemo-(immuno-)therapy of advanced squamous-cell head and neck carcinoma: a multicenter, phase III, randomized study comparing cisplatin + 5-fluorouracil (5-FU) with cisplatin + 5-FU + recombinant interleukin 2.

We carried out an open, randomized, phase III, multicenter clinical trial to compare, in neo-adjuvant setting, the clinical response and toxicity of the combination chemotherapy cisplatin + 5-FU with the same combination plus s.c. recombinant interleukin-2 (rIL-2) in patients with advanced (stage III IV) head and neck squamous-cell carcinoma (HNSCC). Regimen A was the classical Al Sarraf treatment: 100 mg/m2 cisplatin i.v. on day 1 plus 1000 mg m(-2) day(-1) 5-FU on days 1-5 as a continuous infusion. Regimen B was the same as regimen A plus 4.5 MIU/day rIL-2 s.c. on days 8-12 and 15-19. Treatment was repeated every 3 weeks for three cycles. A total of 33 patients were enrolled in the study; 30 were evaluable for toxicity and 28 for response. Seventeen patients were assigned to group A and 16 were assigned to group B. Three patients (20%) of group A and 4 (31%) of group B had a complete response, 9 patients (60%) of group A and 6 (46%) of group B had a partial response, with an overall response rate of 12 patients (80%) for group A and 10 patients (77%) for group B. Two patients (13%) of group A and 3 patients (23%) group B had stable disease; 1 patient (7%) of group A had progressive disease. Thus, there was not a statistically significant difference in response rate between the two groups and therefore there was no benefit from the addition of immunotherapy with rIL-2 to the standard chemotherapy. Both regimens were well tolerated. There were 2 toxic deaths (6.7%), 1 from hematological causes in group A and I from cardiac causes in group B. Myelosuppression and gastrointestinal toxicity, mainly nausea/vomiting and stomatitis, were the most frequent toxicities. The calculated number of patients for the sample has not yet been reached; however, the projection of our present results suggests that it is highly improbable that a clinically significant difference between the two treatment groups will be observed even if the calculated patient sample size is achieved.
