Carboplatin plus Taxol is an Effective Third-line Regimen in Recurrent Undifferentiated Nasopharyngeal Carcinoma

Background

Recurrent undifferentiated nasopharyngeal carcinoma is a chemosensitive disease. Few third-line treatments have been reported.

Methods

Twelve patients (9 males, 3 females; median age 50 years, range, 20-62) with recurrent undifferentiated nasopharyngeal carcinoma were treated with carboplatin AUC 5.5 + paclitaxel (175 mg/m2, 3-hr infusion) on day 1 every 3 weeks. All patients had been previously treated for recurrent disease with a first-line cisplatin-based chemotherapy and a second-line therapy with low-dose continous infusion 5-fluorouracil.

Results

Overall, 54 courses were given (median, 5; range, 2-6). Three patients (25%) obtained a partial response lasting 6, 10 and 26+ months, 1 (8.3%) a minimal response lasting 6 months, and 3 (25%) no change with a median duration of 5 months. The median survival time was 14 months for patients who had a partial or minimal response or no change, and 5 months for nonresponders. Median overall survival was 9.5 months (3-30+). The treatment was well tolerated, and toxicity was manageable.

Conclusions

The combination has a good pallitive role as third-line chemotherapy in recurrent undifferentiated nasopharyngeal cancer.

Concomitant Chemoradiotherapy Followed by Adjuvant Chemotherapy in Parotid Gland Undifferentiated Carcinoma

Aims and background

Undifferentiated carcinoma of the parotid gland is a poor-prognosis lesion. Results in unresectable lesions, treated with radiotherapy alone, are very disappointing.

Methods

Six patients with T3-4 N0-1 inoperable lesions were treated with conventional radiotherapy (64-70 Gy, 2 Gy per fraction 5 times a week) and concomitant cisplatin (100 mg/m2, days 1, 22 and 43). Four weeks after radiotherapy, adjuvant chemotherapy (cisplatin, 80 mg/m2, day 1, + VP16, 100 mg/m2, days 1, 3 and 5, q = 3 weeks, for 3 cycles) was given.

Results

A median dose of 66 Gy (range, 64-70 Gy) was delivered, and all patients recived 3 courses of cisplatin during radiotherapy. Five of 6 patients recived all three chemotherapeutic adjuvant courses. Two months after the end of treatment, 3 CR (50%), 2 PR (33%) and 1 NC (16%) was observed. Median CR and PR duration was 26+ and 10 months, respectively. Median overall survival was 18 months. No severe acute or late toxicity was observed.

Conclusions

Concomitant chemoradiotherapy followed by adjuvant chemotherapy in advanced unresectable undifferentiated parotid carcinoma is feasibile and well tolerated. The high percentage of long-lasting CR is encouraging.

Combined Chemo-Radiotherapy for Stage IV Undifferentiated Nasopharyngeal Carcinoma

Undifferentiated nasopharyngeal carcinoma is a chemosensitive lesion, but its role in the management of local advanced disease is under investigation. Twenty-seven untreated stage IV undifferentiated nasopharyngeal carcinoma patients were treated with radiotherapy (median dose, 66.6 Gy, 1.8 Gy/day) and concomitant cisplatin (100 mg/m2 days 1, 22 and 43). After 4 weeks, patients received, every 4 weeks, 3 cycles with cisplatin (80 mg/m2 day 1) + 5-fluorouracil (1000 mg/m2/day continuous infusion for 96 h). After radiotherapy, we observed 74% complete responses and 26% partial responses; after adjuvant chemotherapy 96% had a complete and 4% a partial response. After a median follow-up of 36 months, 81% of the patients were alive (70% with no evidence of disease). Four-year overall and disease-free survival was 70% and 60%, respectively. Concomitant chemotherapy plus radiotherapy was well tolerated, whereas adjuvant chemotherapy was more toxic. Long-term results were significantly better than those observed with radiotherapy alone.

Stage III-IV Sinonasal and Nasal Cavity Carcinoma Treated with Three-Dimensional Conformal Radiotherapy

Aims and Background

To report the dosimetric data and clinical outcomes of patients with advanced neoplasm of the paranasal sinuses and nasal cavity, treated by three-dimensional conformal radiotherapy.

Methods

Between 2000 and 2005, 31 consecutive patients were treated for locally advanced tumors of paranasal sinuses and nasal cavity. The primary tumor was located as follows: maxillary sinus 15 (48.4%); ethmoid sinus 10 (32.3%); nasal cavity 6 (19.3%). The patients were separated in two groups according to the modality of treatment: group Aincluded 21 patients treated with postoperative three-dimensional conformal radiotherapy with or without chemotherapy; group B included 10 patients treated with radical three-dimensional conformal radiotherapy with or without chemotherapy. The median radiation dose to the planning target volume was 60 Gy (range, 56–63) for patients who underwent complete surgical resection and 68 Gy (range, 64–70) for those who did not have tumor resection or patients with residual disease.

Results

The median follow-up was 42 months. Five-year local tumor control and overall survival actuarial rates were 74% and 72%, respectively, in the postoperative setting, 20% and 25%, respectively, with the primary radiotherapy. Local recurrence was the most common site of failure. No patient developed radio-induced blindness; 4 patients underwent enucleation as part of radical surgery. Dosimetric data are reported.

Conclusions

The local control rate for these tumors remains low. The prognosis depends on localization, tumor stage and treatment modality. Three-dimensional conformal radiotherapy reduces the risk on optical pathways but does not modify outcome.

Radiotherapy Alone or with Concomitant Daily Low-Dose Carboplatin in Locally Advanced, Unresectable Head and Neck Cancer: Definitive Results of a Phase III Study with a Follow-Up Period of up to Ten Years

Aim and background

Radiotherapy is the conventional treatment for locally advanced inoperable head and neck squamous cell carcinoma. However, the poor therapeutic results justify the development of radiochemotherapy combinations. In an attempt to improve local control and survival in patients with stage III and IV unresectable head and neck squamous cell carcinoma and based on the results of our previous dose escalation study, we undertook a prospective multicentric randomized trial.

Materials and methods

From November 1992 through December 1995, a total of 164 patients were randomized to receive radiotherapy alone (arm I) or combined (arm II) with daily low-dose carboplatin.

Results

The 3, 5 and 10-year local-regional recurrence-free survival rates were better in arm II(21.7%, 15.1% and 15.1%, respectively) than in arm I (15%, 10.7% and 10.7%), but without statistical significance (P = 0.11). The 3, 5 and 10-year disease-free survival rates showed the same positive trend for arm II (16%, 6.8% and 6.8% vs 9%, 5.5% and 5.5%, in arm I, respectively), again without statistical significance (P = 0.09). Instead, a statistical advantage was found in overall survival rates at 3, 5 and 10-years (28.9%, 9% and 5.5% in arm II and 11.1%, 6.9% and 6.9% in arm I, respectively) (P = 0.02). The 3, 5 and 10-year local-regional recurrence-free survival rates in stage IV disease were statistically better in arm II (21.5%, 15.9% and 15.9%) than in arm I (12.8%, 7.7% and 7.7%, respectively) (P = 0.04).

Conclusions

Long-term results in both treatment arms of the trial appear less positive than most published series. However, our findings do not exclude that carboplatin may be beneficial, but the benefit in local control must be lower than the 15% assumed to dimension the trial.

Induction chemotherapy with carboplatin and taxol followed by radiotherapy and concurrent weekly carboplatin + taxol in locally advanced nasopharyngeal carcinoma

PURPOSE

Aim of this study was the clinical evaluation of carboplatin-taxol combination in a neoadjuvant and concomitant setting with conventional radiotherapy in loco-regionally advanced nasopharyngeal carcinoma (A-NPC).

METHODS

Thirty patients were treated with three cycles of carboplatin (AUC6) plus taxol (175 mg/m(2)) on day 1 every 3 weeks, followed by weekly carboplatin (AUC1) plus Taxol (60 mg/m2) and concomitant radiotherapy (70 Gy).

RESULTS

We observed the objective complete response rates of 33% (after chemotherapy) and 87% (after chemo-radiotherapy). Treatment tolerability and toxicity were controllable. Three- and five-year progression-free survival were 80 and 75%, respectively, and 3- and 5-year overall survival were 85 and 80% (follow-up 49.5 months). Five-year loco-regional control was 90.3%, and five-year distant metastases-free survival was 85%.

CONCLUSIONS

Neoadjuvant chemotherapy with such protocol represents a feasible, efficient treatment for patients with A-NPC, ensuring excellent loco-regional disease control and overall survival with low incidence of distant metastases.

Docetaxel, Carboplatin and Concomitant Radiotherapy for Unresectable Squamous Cell Carcinoma of the Head and Neck

Concomitant chemoradiotherapy is the most effective treatment of unresectable head and neck cancer. Docetaxel and carboplatin are two active drugs that potentiate radiotherapy. Thirty patients (median age = 56 years; median Eastern Cooperative Oncology Group performance status = 1) received radiotherapy (70 Gy, 2 Gy/d, 5 d/wk) concurrent with carboplatin AUC 0.3 to 0.5 on day 1-5, weeks 1, 3, 5, 7, and docetaxel 15 to 25 mg/m2 on day 4 of weeks 2, 4, and 6. Site of unresectable squamous cell carcinoma was as follows: oropharynx, 41%; hypopharynx, 27%; oral cavity, 16%; and larynx, 16%. Stage was III in 13% and IV in 87%. In 11 patients, pharmacokinetic parameters were evaluated. Acute G4 toxicity was as follows: neutropenia, 20%; mucositis, 33%. We had the following acute G3 toxicities: mucositis, 40%; neutropenia, 37%; dermatitis, 23%; and anemia, 13%. The maximum tolerated dosage was area under the curve 0.5 for carboplatin and 20 mg/m2 for docetaxel. Median radiotherapy dose was 69 Gy, and 175 out of 210 courses (83%) were administered. At the end of the treatment, we had 20 complete responses (CR) (67%), 9 partial responses (30%), and 1 no change (3%). After radial neck dissection, 2 patients achieved a CR (overall CR = 73%). After a median follow-up of 2.5 years, we had a 3-year local progression-free survival of 85%, failure-free survival of 69%, and overall survival of 60%. A significant increase of Cmax of carboplatin concentration was noted at the beginning of weeks 3, 5, and 7. Total plasma platinum raises during each course of 5 days of carboplatin without reaching a steady state. Carboplatin, docetaxel, and concomitant conventional radiotherapy is a feasible and effective treatment of unresectable head and neck cancer. The concurrent administration of two drugs does not alter pharmacokinetic drug behavior compared with single-agent data.

Postoperative Adjuvant Chemoradiotherapy in Older Patients With Head and Neck Cancer

BACKGROUND

In head and neck cancer, the locoregional failure of patients with positive margins, vascular or perineural invasion, and extracapsular spread is high and results in poor survival.

OBJECTIVE

To assess the effect of adjuvant chemoradiotherapy in improving treatment outcomes among older patients with head and neck cancer.

METHODS

Forty patients undergoing radical surgery (median age, 73.5 years [range, 70-78 years]) were enrolled (35 men and 5 women; Eastern Cooperative Oncology Group performance status, grade 0-2). Disease sites included the oral cavity (10 patients), oropharynx (12 patients), hypopharynx (8 patients), and larynx (10 patients); pathological TNM classifications included T1 N2 (8 patients), T2 N1-2 (12 patients), T3 N0-2 (8 patients), and T4 N0-2 (12 patients), with the following poor prognostic factors: positive margins (6 patients), vascular invasion (14 patients), neural invasion (16 patients), and extracapsular spread (26 patients). All patients were treated with carboplatin (30 mg/m2 on days 1-5 of weeks 1, 3, and 5) concomitant with radiotherapy (54.0 Gy to all risk volumes plus 10.0 Gy to high-risk volumes; 5 daily fractions of 1.8 Gy each per week).

RESULTS

No grade 4 toxicity was observed. Grade 3 toxicity included mucositis (10 patients), neutropenia (6 patients), dermatitis (2 patients), and thrombocytopenia (1 patient). The radiotherapy dose administered was 52.0 Gy to all risk volumes plus 10.0 Gy to high-risk volumes. Thirty-two patients (80%) received 3 cycles, 6 (15%) received 2 cycles, and 2 (5%) received 1 cycle. Three-year survival was as follows: disease-free survival, 58%; overall survival, 64%; and local control, 79%.

CONCLUSIONS

Adjuvant chemoradiotherapy may be successful in fit older patients. The results of adjuvant chemoradiotherapy were better than those observed in a comparable group treated with radiotherapy alone and were similar to those observed in a younger group with the same poor prognostic factors treated with adjuvant carboplatin plus radiotherapy.

Docetaxel and vinorelbine in recurrent head and neck cancer: pharmacokinetic and clinical results

The purpose of this study was to evaluate pharmacokinetic parameters, efficacy, and toxicity of a combination of docetaxel (DTX) and vinorelbine (VNB) in recurrent heavily pretreated squamous cell head and neck cancer. Twenty-nine patients previously treated with concomitant chemoradiotherapy (n = 14), surgery plus radiotherapy (n = 13), surgery+concomitant chemoradiotherapy (n = 1) and radiotherapy alone (n = 1) were enrolled; 9 patients had received 1 or more courses of palliative chemotherapy. Twenty-one patients had a local-regional recurrence, and 8 patients had metastases. The doses were 80 mg/m2 for DTX and 20 mg/m2 for VNB on day 1 every 21 days for a maximum of 6 cycles. Pharmacokinetic evaluations were performed on 24 patients; in a group of 12 patients, VNB administration immediately followed DTX infusion (schedule A), and in 12 patients VNB administration was immediately followed by DTX infusion (schedule B). Twenty-nine patients received a total of 137 cycles (median per patient, 5). Neutropenia was the most frequent and severe side effect (grade IV in 79%; grade III in 21%). Grade IV (7%) and III (14%) infections were observed in the first 12 patients; ciprofloxacin prophylaxis in the following 17 patients reduced the severe toxicity to 0%. The overall response rate was 49%, which included 3 of 29 complete responses (10%) and 11 of 29 partial responses (38%). Median complete and partial response durations were 20+ and 5.5 months, respectively. Overall median survival was 10 months (range, 2-30+). The mean values of area under the curve, mean residence time (MRT), and C(max) of VNB were significantly lower for schedule A than for schedule B. The mean values of VNB clearance were significantly higher for schedule A than for schedule B. Neutrophil count at the nadir was much lower for patients receiving schedule B. The DTX-VNB combination is effective in heavily pretreated patients with a short-lasting manageable toxicity. Pharmacokinetic evaluations suggested that the sequence DTX --> VNB is safer than the sequence VNB --> DTX.

Feasibility and long-term results of autologous PBSC transplantation in recurrent undifferentiated nasopharyngeal carcinoma

BACKGROUND

Recurrent undifferentiated nasopharyngeal carcinoma (UNPC) is a chemosensitive illness. Here we report long-term results of high-dose chemotherapy (HDC) as late intensification, with autologous peripheral blood stem cell (PBSC) support.

METHODS

Six patients (5 men, 1 woman; median age 41years; median ECOG PS = 0) with recurrent UNPC (local, 2; local + nodal, 2; bone metastasis, 2) have been enrolled. All patients had been previously treated with neoadjuvant chemotherapy and radiotherapy; 3 of 4 local relapses had received a re-irradiation. Every patient received three courses of cisplatin + epirubicin and 1 cycle of epirubicin followed by PBSC collection. A median of 7.2 x 10(6)/kg (range, 4.5-18) CD34+ cells were reinfused. HDC was according ICE scheme: ifosfamide, 2.5 g/m(2)/d, + carboplatin, 300 mg/m(2)/d, + VP-16, 300 mg/m(2)/d days 1 through 4.

RESULTS

After conventional chemotherapy, we had 1 CR (16%), 3 PR (50%), and 2 NC (34%). After HDC, we had 4 CR (66%),1 PR (17%), and 1 MR (17%). Toxicity was manageable. After a median follow-up of 30 months (range, 14-50), two patients are alive without disease (34%), one is alive with bone disease (16%), and three (50%) died of disease at 16, 18, and 24 months.

CONCLUSIONS

HDC has an acceptable toxicity, can convert PR in CR, and seems effective, with long-lasting CRs.

Phase II randomized trial comparing vinorelbine versus vinorelbine plus cisplatin in patients with recurrent salivary gland malignancies

BACKGROUND

Some previous studies have shown that vinorelbine (VNB) is active in recurrent salivary gland tumors.

METHODS

Between April 1993 and April 1997, 36 patients in a Phase II randomized trial received either cisplatin, 80 mg/m(2), on Day 1 plus VNB, 25 mg/m(2), on Days 1 and 8 (every 3 weeks) (for a minimum of 3 cycles (Arm A [16 patients]), or VNB, 30 mg/m(2)/week, (for a minimum of 9 wks) (Arm B [20 patients]). There were 23 males and 13 females with a median age of 59 years (range, 20-74 years) and a median Eastern Cooperative Oncology Group performance status of 1 (range, 0-2). Four patients had been treated with prior surgery (S) or radiotherapy (RT), 27 patients had been treated with S plus RT, and 5 patients had been treated with S plus RT plus mitoxantrone. Eighteen patients had major salivary gland tumors, and 18 patients had minor salivary gland tumors; 9 patients had adenocarcinoma, 22 patients had adenoid cystic carcinoma, 1 patient had a malignant mixed carcinoma, 3 patients had undifferentiated carcinoma, and 1 patient had a mucoepidermoid carcinoma. The site of recurrence was local in 16 patients, local plus metastatic in 5 patients, and metastatic only in 15 patients. These characteristics were well balanced between the 2 arms.

RESULTS

In Arms A and B a complete response (CR) was noted in 3 patients (19%) and no patients, respectively; a partial response (PR) was noted in 4 patients (25%) and 4 patients (20%), respectively; no change was noted in 6 patients (37.5%) and 9 patients (45%), respectively; and progressive disease was noted in 3 patients (19%) and 7 patients (35%), respectively. The median duration of the CR was 15+ months (range, 6-27+ months) and for PR the median duration was 7.5 months (range, 3-11+ months) and 6 months (range, 3-9 months) in Arms A and B, respectively. Number of patients surviving > 12 months was 6 versus 1 in Arms A and B, respectively (P < 0.05). Grade 2-3 nausea and emesis was statistically higher (P < 0.001) in Arm A; there was no significant difference with regard to other side-effects between the two treatment arms.

CONCLUSIONS

VNB is a drug with moderate activity in salivary gland malignancies. The combination of cisplatin plus VNB was found to be more active than VNB alone, with a good number of CRs and long-term survivors reported in the current study.

Radiation therapy and chemotherapy in the conservative treatment of carcinoma of the anal canal: survival and late morbidity in a series of 25 patients

Combined radiation therapy and chemotherapy have been reported to produce a high incidence of complete regression of epithelial cancer of the anal canal. Our group has treated 25 patients since June 1986. Treatment included chemotherapy (first period: Mitomycin C + 5-Fluorouracil; second period: Carboplatin + 5-Fluorouracil) and simultaneous whole-pelvis irradiation (50.40 Gy). Our results confirm that radiochemotherapy can achieve good local control: all patients were in complete clinical remission three months after the completion of combined therapy. Seven, patients developed recurrences; the actuarial survival rate was 78.5% and the disease free survival rate 67%. Acute toxicity was tolerable, but a relatively high number of patients exhibited chronic treatment-related symptoms. In order to reduce late side effects, other studies are necessary to explore if, in patients with small tumors, less extensive locoregional treatment can be effective without reducing the survival rate.

[The results of sandwich adjuvant radiotherapy in 2nd- and 3rd-stage rectal adenocarcinoma. The authors' personal experience]

From January, 1985, to June, 1993, 125 patients with stages B2-C adenocarcinomas of the rectum were submitted to pre- and postoperative irradiation according to Thomas Jefferson University protocol guidelines. Five hundred cGy were administered as a single preoperative dose 24 hours before surgery using parallel opposed (AP-PA) treatment fields including the whole pelvis. Pathologic samples were classified following the Astler-Coller staging criteria. Forty-seven patients had no postoperative treatment because their disease stage was A, B1 or D, 11 for refused consent and 9 postoperative complications preventing any further therapy. Seventy-eight patients concluded the treatment schedule and are assessable for response. Radiotherapy total dose consisted of 4400-5000 cGy administered over 5-6 weeks: the patients were treated with megavoltage photons (15-MeV photons) and one dose fraction of 2 Gy was delivered daily, 5 days a week, with the "box" or the "three-field" technique. Median follow-up time was 50.2 months from the beginning of treatment for all the patients in our series (range: 18-120 months). Radiation therapy was well tolerated: 5 patients had severe diarrhea and 2 had small bowel obstruction which required surgery. Local recurrences were observed in 13 of 78 patients (16.7%). Overall actuarial survival at 5 years was 66.8%. Our results confirm the efficacy of this treatment, which is in agreement with international literature data. However, no difference was seen relative to the results obtained with postoperative irradiation alone. We conclude that sandwich radiotherapy can be an effective tool for the local control of rectal adenocarcinoma, with acceptable morbidity, even though it fails to prevent metastases.

[RAdio-chemo-surgical combined treatment of non-small cell lung carcinoma N2]

As yet, no optimal treatment for stage-IIIA non-small-cell lung cancer (NSCLC) has been established. Particularly, in the patients with stage-IIIA N2 disease, surgical resection for cure is limited to few selected patients. Of late, a number of studies have suggested that such treatment modalities as chemotherapy, radiotherapy and surgery might be combined to improve treatment efficacy. Based on these conclusions, a cooperative study for N2 NSCLC patients was performed. Treatment included continuous CDDP infusion (6 mg/m2/day) and concomitant irradiation. Fifteen patients were examined. After neoadjuvant treatment, 4 patients were found to have unresectable lesions for local disease progression or metastasis. Eleven patients underwent complete resection (73% resectability). Follow-up ranged 6 to 32 months: 6 patients are now free from relapse (respectively at 31, 28, 23, 14, 12 and 3 months) and 1 is alive with adrenal gland metastasis. Overall and disease-free survival rates are 40.6% and 31.5%, respectively. Our preliminary results indicated that this protocol is well tolerated. Resectability was good and tumor sterilization rate was satisfying (complete T and N sterilization in 6 cases, sterilization of either T or N in 3 cases). The patients with non-adenocarcinoma histology exhibited better local control and prognosis than those with histologic diagnosis of adenocarcinoma.

[The use of cisplatin as radiosensitizing agent in advanced tumors of the head and neck. Randomized study]

This study was aimed at assessing whether c-DDP administration immediately before radiotherapy could increase frequency and duration of objective responses, as well as survival, in patients affected with locally advanced stages of squamous carcinomas of the head and neck. All patients had already undergone two induction cycles according to the CABO schedule. Ninety-six of 108 treated patients could be evaluated. Treatment schedule consisted in: 1) randomized distribution of patients into two groups before induction chemotherapy; 2) two cycles of induction chemotherapy according to the CABO schedule in all patients; 3) radiation therapy: the patients in group A were given 5 mg/mq of i.v. cisplatin, 30-60 minutes before each session. The results from the two groups were compared and no significant differences were observed regarding objective response (82.5% in group A vs. 86% in group B), response duration and overall survival rates. Even though toxicity was higher in the patients in group A, therapeutic protocol never needed be modified.

[Treatment of N2-3 pulmonary carcinoma. Preoperative radio-chemotherapy]

Preoperative integrated neo-adjuvant radio-chemotherapy was performed in 8 patients suffering from NSCLC bronchial carcinoma at stages IIIA-IIIB (N3 mediastinal). After treatment, 7 patients underwent apparently radical pulmonary exeresis, whereas the patient with adenocarcinoma (T2 N2 M0) was not operated due to the recurrence of disease following supraclavicular lymph node metastasis. Preoperative radio-chemotherapy allows the sub-staging of the disease and the insertion of these patients into the operating programme.

[The use of electrons in oncologic radiotherapy: our experience]

The authors describe the interaction of electrons with tissues, the characteristics of depth isodose curves with sharp dose fall-off. These characteristics reduce the utilization of electron therapy only for tumors situated some 5 cm depth below the skin surface and with regular surface. The authors report their experience from 1978 in the treatment of vulvar carcinoma, chest-wall recurrences from breast carcinoma, and cutaneous lymphomas. All these neoplastic diseases were treated with electron beam of adequate energy. Initially betatron was used, successively a linear accelerator (Siemens) about for two years. Results obtained in the treatment of vulvar carcinoma are reported. Two and five years disease free survival rates was respectively 33% and 19% (it is remarked the importance of prophylactic treatment on inguinal lymphnodes). Local control observed in 44 patients with cutaneous lymphomas was 85% until three years; a greater number of recurrences was observed in centrocytic-centroblastic lymphomas. Moreover, local control of breast recurrences was 65% with 5 years survival rate of 22% (34% in patients with only one skin recurrence). Only 22% of the further local failures appear within the treatment field while 78% appear out of field.

[Preoperative endocavitary curietherapy of stage Ib-IIa-IIb cervical carcinoma. Personal observations]

From 1980 through 1984, 41 patients with squamous cell cervix carcinoma and 1 with adenosquamous carcinoma were treated with preoperative irradiation. Clinical stages were Ib in 6 patients, IIa in 24, and IIb in 12. At surgery, lymph node metastases were found in 5 cases, and residual tumors in 8. The latter risk patients were given further external radiotherapy after surgery. Overall three-year survival rates for FIGO stage Ib was 100%; 91.6% for stage IIa, and 83% for stage IIb (minimum follow-up: 3 years). Two patients died from locoregional recurrence of the disease 12-24 months after the treatment, and 2 from distant metastases; 5 patients have showed signs of local improvement. Our results seem to point to pelvic lymph node involvement as the major prognostic factor: in fact, 40% only of the patients with involved lymph nodes is alive. Actuarial survival rates show 90.4% of patients to be alive at 5 years. Tolerance to the combined use radiotherapy and surgery was fair: no severe side-effects were observed. Even though our results are encouraging, a randomized study is still recommended to verify the actual value of this treatment versus combined surgery and radiotherapy or radiotherapy alone.

[Quadrantectomy and adjuvant radiotherapy in carcinoma of the breast. Initial results of our cases]

The conservative treatment of early breast cancer always requires irradiation of residual mammary tissue. The preliminary results obtained in 45 early breast cancer patients, who received quadrantectomy plus axillary dissection, followed by radiation of residual breast are reported. Radiation was performed by the two opposed field technique. In some cases the residual breast tissue was compressed using a special accessory provided with the Theratron 780. In addition to the tumor dose of 50 GY, 10 GY boots was added to the surgical scar using 7 MeV electrons. The 6 patients with positive axillary nodes received 6 courses of adjuvant chemotherapy (CMF) after radiotherapy. All patients are currently alive and free of disease. The 64% (29 patients) were followed up for at least 5 years, and 36% (16 patients) for at least 3 years. Only 2 cases of local recurrence were encountered (4.4%). The esthetic result was satisfactory in all cases. No side effects due to treatment were noted.
