RESUMEN

From 1970 to 1987, 213 cases of carcinoma of the cervical stump were accrued in a multi-institutional prospective cooperative study. This group accounted for 5.5% of cervical carcinoma diagnosed during the same period. 13 had in situ carcinoma and 200 had invasive carcinoma (96% squamous cell carcinoma, 4% adenocarcinoma). Radiotherapy alone (external and brachytherapy) was given to 77%, brachytherapy and surgery to 15% and surgery alone to 8%). FIGO stage distribution was: I (31%), IIa (15%), IIb (27%), IIIa (5%), IIIb (17%) and IV (5%). Five-year locoregional control per stage was 100% in Ia, 85% in Ib, 82% in IIa, 71% in IIb, 45% in IIIa, 54% in IIIb and 30% in IV. Corrected 5-year survival per stage was 82% in Ib, 78% in IIa, 73% in IIb, 69% in IIIa, 38% in IIIb and 0% in IV. The diameter of disease in stage II strongly influenced the 5-year locoregional control (81% for tumours of less than 3 cm vs. 68% for tumours more than 3 cm). Lymphangiogram was associated with a 44.5% 5-year locoregional control when positive vs. 74% when non-positive. Brachytherapy was advantageous in obtaining locoregional control in patients receiving external irradiation and brachytherapy: 81.5% vs. 38.5% in patients treated with external radiotherapy alone. Surgery was performed only for in situ carcinoma and for part of stages Ia, Ib and IIa. There is no significant difference in locoregional control at equal stage between radiotherapy alone and treatment schemes including surgery. However, lethal complications were observed in 6% of the patients of the surgical group as compared to 0.6% of the patients treated with radiotherapy alone. Radical radiotherapy seems to provide similar results of locoregional control and survival at equal stages in carcinoma of the cervical stump compared to carcinoma developed on an intact uterus. The rate of severe complications reported with the French-Italian glossary is 13% for G3 and 3% for G4, which is close to the observed rate during the same period in our series of radical radiotherapy to the intact uterus.

RESUMEN

From January 1976 to December 1978, 581 previously untreated patients with Stage II carcinoma of the uterine cervix were treated by radiotherapy alone in nine departments of radiotherapy in France. This retrospective analysis was undertaken in an attempt to evaluate the therapeutic results and prognostically significant factors. The initial clinical staging and the therapeutic guidelines were as outlined at the U.T. M. D. Anderson Hospital in Houston; all our patients were treated by standardized protocols combining external beam irradiation and intracavitary irradiation with cesium sources. The overall locoregional control rate was 83.2%, with total disease control of 74.5%. Uncorrected actuarial survival rates are 76% at 3 years and 68% at 5 years. The incidence of severe posttherapeutic complications is 7.2%. Clinical substaging, patient's age at the time of the diagnosis, lymphangiogram findings, and tolerance to external irradiation were all found to have prognostic significance. According to those findings, the possibilities of improving the results are discussed.

RESUMEN

A French Cooperative study of 1383 cases with invasive carcinoma of the intact uterine cervix treated with radiation therapy alone, using the guidelines provided by G. H. Fletcher led to the following conclusions: The techniques of treatment were easily reproducible in 9 French centers, working in a prospective cooperative study; Results similar to those of the original study were achieved in Stages I and IIA (MDAH substaging) with a locoregional failure rate of 7%; In Stage IIB, the locoregional failure rate of 16% is also comparable in both studies; Locoregional failures in Stage III are slightly lower than those reported in Houston, probably reflecting differences in patient's prognostic factors in France and Texas; The 5-year survival rate obtained in advanced Stages (UICC FIGO staging) are among the highest in the literature (76% in Stage IIb, 62% in Stage IIIa and 50% in Stage IIIb); The rate of severe complications remains acceptable and decreased throughout the study thanks to a better use of computer dosimetry.

RESUMEN

This paper is the report of a dosimetric study of 79 urinary complications after radical radiation treatment (1975-1979) of 624 cervical uterine tumors. Treatment consisted of external irradiation (25 MeV linear accelerator) and intracavitary irradiation (Fletcher-Suit-Delclos applicator). Dosimetric-computerized studies were expressed as the maximum bladder dose on the trigone, as proposed by the I.C.R.U. Bladder doses were actually studied as a function of intracavitary irradiation and intracavitary + external irradiation. The results show a significant difference in patients with and without complications based on the dose reaching the bladder. The relative contribution of external therapy and intracavitary irradiation and their value can serve as one of the primary indicators for predicting complications. These values should be determined before placement of intracavitary sources. We found that the dose to the critical organs cannot be defined as a single number. These results argue in favor of adapting individual patient therapy based on rectal and bladder dosimetry and may be adjustable to all treatment modalities.

RESUMEN

Interstitial irradiation is a technique currently used in the treatment of bladder cancer. We report the data on 205 patients (177 men and 28 women) treated in eight French centers. The patients had received the following treatment: a short course of pre-operative pelvic irradiation, followed by surgery consisting of partial cystectomy or tumor resection, and implantation of plastic tubes filled with inactive lead wires, which were replaced by iridium 192 wires. The tumor characteristics were: transitional cell carcinoma, 88.8%; mean size of the tumor, 29 mm; pathological stages: pTis, 1; pT1, 98; pT2, 66; pT3a, 26; pT3b, 9; pT4, 1; unknown, 4 respectively; surgical lymph node status: N+, 3; N-, 118; no node dissection, 84. The mean follow-up was 51 months. Intravesical failures were seen in 35 patients (17.0%), 25 (71.4%) of them without metastases or regional recurrences. Twenty-one patients (10.2%) presented distant metastases, 2/3 of them suffered no bladder relapse. The 5-year survival, calculated according to the Kaplan-Meier method (all causes of death taken together) was 77.4% for the T1, 62.9% for the T2, and 46.8% for the T3. Fifty-three patients had immediate side-effects and three died from surgical complications. Twenty-nine patients had delayed bladder side-effects (haematuria, fistula, chronic cystitis). Six patients presented an ureteral stenosis. Of the disease-free survivors, 96.1% retained the bladder function. Three factors were significantly predictive of delayed side-effects: partial cystectomy, pre-operative radiotherapy total dose, and linear activity of the wires (p < 0.01). Comparing our results to different authors' series interstitial irradiation is likely to provide a high local and general control of the disease and good quality of life in patients with selected tumors.

RESUMEN

PURPOSE: To determine independent prognostic factors in a group of 1875 patients with invasive carcinoma of the intact uterine cervix treated with radiotherapy alone in a French cooperative study from 1970 to 1993. MATERIALS AND METHODS: Patients were staged according to the UICC-FIGO and MDAH substaging. The distribution per FIGO stage was Ia-Ib: 25.5%; IIa: 12%; IIb: 29%; IIIa: 5%; IIIb: 25%, and IV: 3.5%. Ninety-two percent had squamous cell carcinoma. The maximum diameter of the clinically detectable cervical disease was less than 3 cm in 24.5% of Stages I-II and in 10% of Stages III-IV, more than 5 cm in 13.5% of Stages I-II, and in 16% of Stages III-IV. Nodal involvement was shown on lymphangiogram in 16% of Stages I-II and in 32.5% of Stages III-IV. RESULTS: 1) Univariate analysis of Stages I and II: stage, cervical disease diameter, and nodal involvement are significant prognostic factors. Five-year specific survival rate (5ySS) is 83.5% in Stage Ib, 81% in IIa and 71% in IIb. Five-year disease-free survival rate (5yDFS) is 86% in tumors less of 3 cm, 76% in tumors of 3 to 5 cm, and 61.5% in tumor larger than 5 cm. Lymphangiogram strongly influences the 5-year pelvic disease-free survival rate (5yPDFS): respectively, 90% in nonpositive lymphangiogram vs. 65% when positive. A significant drop in specific and disease-free survival is observed (10 and 14%, respectively (p = 0.04) when comparing adenocarcinoma and squamous cell carcinoma. Age is a significant prognostic factor for specific survival because patients aged less than 30 years old have 91% vs. about 75% for patients over 30 years (p = 0.03). 2) Univariate analysis of Stages III-IV: Stage and positive lymphangiogram are predictive factors for relapse and death. The MDAH substaging is more reliable to predict the probability of pelvic disease-free survival in Stage III. At 5 years, the FIGO Stages IIIa and IIIb have a rather similar PDFS (65% vs. 59%). Conversely, the difference of survival rates between MDAH Stage IIIA and Stage IIIB is more demonstrative (69% vs. 47.5%). 3) Multivariate analysis (Cox P. H. R. model). Nodal involvement and stage remain significant for all three models in all stages (p < 0.0001). Age above 70 years influences specific survival for Stage I-II (p = 0.01). Tumors larger than 5 cm and adenocarcinoma also appear to be independent prognostic factors for specific and disease-free survival in Stage I-II (p = 0.05 and p = 0.005, respectively). CONCLUSIONS: The relevance of tumor size (less or greater than 4 cm) is now recognized in the 1995 revised FIGO staging in Stage Ib but unfortunately not in other stages. Tumor size per stage and nodal status should be systematically recorded to allow a better prediction of failure rates and to compare literature reports.

RESUMEN

Based on the synergistic action of 5-fluorouracil (5-FUra), cis-dichlorodiamminoplatinum(II) (cis-DDP) and gamma-rays, which was suggested in experiments on murine tumours, a sequential treatment combining irradiation and chemotherapy for human solid tumours known to be resistant to conventional treatments has been developed. A pilot study was carried out on 30 patients with recurring head and neck cancers previously treated by radiotherapy and surgery. The good tolerance and the initial results justified applying this protocol to previously untreated cases. The second study involved 40 patients with stage III and IV tumours. After 3 cycles of combined radio- and chemotherapy followed by a conventional radiotherapy, 78% were good responders (51% in complete remission). Oropharynx and oral cavity, without base of tongue, have a 51% actuarial survival at 3 years when they achieved an early complete remission.

RESUMEN

According to respective proportions of evolutive status groups, results of multivariate studies are difficult to interpret. Among the 1099 cases of local form of prostate cancer, treated by radiotherapy from 1975 to 1982 in 16 French Anticancer Institutes, we can observe two homogeneous status groups of patients: disease-free survivors (285 cases) and patients who died of prostate cancer (278 cases). These correspond to 51% of the whole population. Among other things, they are comparable in size, for age at the beginning of radiotherapy and for delay between histologic diagnostic and radiotherapy. We chose to analyse them using multivariate analysis. To take survival into account, we used a Cox model and Kaplan-Meier curves; the group deceased of prostate cancer was further analyzed by a tree-structured regression method. The Cox model and the Kaplan-Meier curves confirmed two main explicative factors: Stage (p < 0.0001) and tumor grade (p < 0.001). Poorer evolution occurs in extracapsular forms and grade I has better survival than others. The tree-structured regression method indicates two other pejorative factors: hormonotherapy prior to radiotherapy and the presence of cardiovascular pathology. Though the pelvic dose does not appear to be a main explicative factor, it seems to improve survival and delay between radiotherapy and recurrence or metastasis in some categories of cases. Other factors such as tumor dose, age and delay between diagnosis and radiotherapy were not found to be significant. These results cannot be extended to the whole population for which they do not constitute a predictive study. We consider them as "baseline data".(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Although cancer of the penis is a rare disease, we have collected 506 cases through a multicentric study. In the present study we analyse the results obtained from 259 patients treated by interstitial brachytherapy from 1959 to 1989. Among the 259 patients, 184 males had exclusive brachytherapy (group A) while 75 received a combination of surgery and brachytherapy and/or external beam irradiation (EBI) (group B). Five- and 10-year survival rates are, respectively: overall survival, 66 and 52%; cause-specific survival, 88 and 88%; disease-free survival, 78 and 67%. One hundred and forty-three patients in group A (78%) and 48 (64%) in group B avoided mutilation of the penis while late side effects occurred in 137/259 patients (53%). Survival depends on the volume of the tumor and the presence of involved nodes; systematic groin dissection does not however seem advisable.

RESUMEN

Eyelid localisation of non-Hodgkin's lymphoma is rare, and even more so when it is bilateral. We report a 58 year-old man who presented with an eyelid localisation of lymphoplasmacytoid lymphoma. The initial treatment was chemotherapy with good improvement but the relapse lead us to give radiotherapy with no further relapse 20 months later. Radiotherapy is the current treatment of localised eyelid lymphomas with excellent results. The prognosis is related to the initial staging and the 10-year survival rate is close to 80%.

RESUMEN

PURPOSE: Retrospective analysis of the results of radiotherapy in localized prostatic adenocarcinoma. Complications were excluded. PATIENTS AND METHODS: Six-hundred-and-ten T1-T2 adenocarcinomas of the prostate were treated with continuous courses of external beam radiation therapy in 19 participating Institutes between January 1983 and January 1988. The mean follow-up was 10.4 years; the mean age of patients at the beginning of radiotherapy was 68.5 years. RESULTS: A 10-year, local control had been achieved in 86% of T1-T2 (81.4% for T2). The 5- and 10-year metastatic relapse rates were 25.3% and 30% (29% and 38.1% for T2), respectively. At 10 years, 62.4% of T1-T2 were recurrence-free; overall survival rate was 45.8% and cause-specific survival rate was 70.5%; 29.9% of T1-T2 patients were alive and disease-free. T category (TNM), pathologic grade, pelvic lymph node status, local tumor control, and obstructive ureteral symptoms were correlated with survival. The influence of pelvic nodes radiation, dose, overall treatment time, previous endocrine treatment, and transuretral resection was not significant for disease-free survival (alive and disease-free) and other endpoints. CONCLUSION: There was no difference between the French series (1975-1982 and 1983-1988). The results of the literature are comparable to ours. As far as prognostic factors are concerned, this report provides evidence that the explainable variables which influence survival depend on the tumor and patient status.

RESUMEN

We describe a case of cutaneous malignant melanoma metastatic to the iris and the angle 31 months after excision of the primary tumor in a 37-year-old caucasian female patient. The patient who had numerous metastases (lung, liver, cerebrum, skin) suffered from secondary glaucoma and died 5 months after the discovery of the intraocular metastases. The glaucoma was treated with medications and cyclocryotherapy. There was no response of the iris metastases to cyclical combined chemotherapy.

RESUMEN

PURPOSE: The purpose of this study was to contribute to the evaluation of long-term external beam radiation treatment in patients with subfoveal occult choroidal neovessels complicated with pigment epithelium detachment in age-related macular degeneration. MATERIALS AND METHODS: This was a retrospective study of ten patients with a mean age of 75 years and a mean follow-up of 18.7 months. External beam radiation of 14.4 Gy was administered with a daily dose of 1.8 Gy. The efficacy of the treatment was assessed based on visual acuity, the size of the membrane and the persistence or not of neovascular activity. RESULTS: We observed stabilization of visual acuity in 44% of the cases at 6 months but only in 20% at 19 and 30 months. The mean initial visual acuity was measured at 0.2 at presentation and 0.1 at the final evaluation. At the end of the study, 60% of patients attained the level of legal blindness; 90% of patients developed a disciform scar, with persistence of neovascular activity in 27% of the cases. On fluorescein angiography, the size of pigment epithelium detachment increased more than one optic disc diameter in 20% of the cases at 1 year. On the other hand, no radiation complication was observed. DISCUSSION: The visual and anatomical results of our study are similar to the natural progression of occult neovascular membrane. External beam radiation at a dose of 14.4 Gy did not seem to provide a long-term benefit in the treatment of subfoveal occult neovessels associated with pigment epithelium detachment.

RESUMEN

A sixteen-year-old white girl with peripheral neurofibromatosis (NF1), who had been treated for a glioma of the optic nerves and chiasma developed a choroidal mass in her only functional eye. After a transchoroïdal biopsy, the pathologic examination disclosed a choroïdal melanoma of epithelioid cell type, using morphological criteria as well as an immunohistochemical study. After treatment with a ruthenium plaque, the tumor completely regressed over 4 months. According to the data of the literature, neurofibromatosis seems to predispose to the development of uveal melanomas.

RESUMEN

Fifty-seven uveal malignant melanomas (T2: 36.8%; T3: 49.1%) were treated between 1983 and 1989 with Cobalt 60 or/and Ruthenium 106 Rhodium 106 plaques. The mean follow-up was 32 months (from 6 to 69 months). A diminution of tumor size was observed in 88% of the cases, either rapid and marked (57%), or slower and more moderate (31%). A multivariate study showed the radiation dose administered to the tumor edge to be the most significant parameter associated with the tumor control. Seven patients developed metastases, and the probability of survival at 60 months was 83.3%. This probability was identical to that of 59 comparable patients treated, some years before, by enucleation. The most frequent complications were radiation retinopathy (28.1%) and retinal detachment (15.8%). The treated eye was retained in 86% of cases. In 57% of treated eyes, vision remained better or equal to 0.1. The predictive parameters of vision impairment after treatment seemed to be tumor size, tumor site near the macula and the optic nerve, and the radiation dose to the tumor base. The use of Ruthenium 106 Rhodium 106 appeared to be advantageous in controlling the disease as well as in reducing the incidence of complications.

RESUMEN

PURPOSE: To analyze 65 patients with uveal melanomas treated with cobalt plaque therapy with regards to mortality, visual results and complications. PATIENTS AND METHODS: Most of the melanomas were large (T3: 52.5%), with a mean largest dimension of the base of 11 mm, and a mean thickness of 6 mm. Most of the tumors were located in the choroid (95%), with an anterior margin behind the equator (65%), and a posterior margin at less than 3 mm of the disc and/or of the macula (69%). The plaque radiotherapy delivered a mean dose of 95 Gy to the tumor apex, either with a cobalt plaque alone (51 cases), or in association with a ruthenium plaque (14 cases). The mean follow up period was over 8 years. RESULTS: The local control was achieved initially in 86% of the eyes. The estimated melanoma specific survival rate was 83% after 5 years and 74% after 10 years. The main parameter associated with the metastases was the largest dimension of the base (p < 0.01). The eye was retained in 83% of the cases. The probability of keeping a vision better than or equal to 0,1 was 39% after 5 years and 27% after 10 years. The main parameter associated with the visual loss was the tumor size (p < 0.01). The complications included cataract (39%), radiation retinopathy (34%), with maculopathy (19%) and/or papillopathy (13.5%), vitreous hemorrhages (22%), neovascular glaucoma (15%) and retinal detachment (12%). CONCLUSION: These results supported the value of cobalt plaque radiotherapy in the management of uveal melanomas.

RESUMEN

PURPOSE: The purposes of this study were to evaluate the incidence of uveal melanoma in France in 1992, to describe the characteristics of the tumors and their treatments. METHODS: This was a retrospective and multicentric study. First a questionnaire was sent to 4575 French ophthalmologists asking whether they had established a diagnosis of uveal melanoma during 1992, and if so, to describe the tumor and its management. Then the patients files were reviewed in the specialized treatment centers (Paris, Lyon, Nice, Strasbourg, Bordeaux, Clermont-Ferrand). All the data were statistically analysed. RESULTS: 412 new cases of uveal melanomas were registered (incidence 0.7/100000) affecting 234 females and 178 males. The cases ranged in age from 7 to 93 years (mean 61.5 years). There were 5 (1%) isolated tumors of the iris, 75 (18%) of the ciliary body, either isolated (10%) either associated to iris and/or to choroïdal tumors and 332 (81%) choroïdal melanomas. 201 (53%) tumors were posterior to the equator and 153 (40%) had a margin at less than 3 mm of the optic disc; 87 (21%) melanomas were detected in asymptomatic patients. In 29 (7%) other cases, the diagnosis was established after enlargement of the tumor. In all other eyes, symptoms were present. 17% of the melanomas were T1, 34% were T2, et 48% were T3. 353 (86%) melanomas were pigmented, 30 (7%) were achromic and 29 (7%) of the mixed color type. 156 (38%) tumors were associated with a retinal detachment. In 12 cases (3%), at presentation there was an extrascleral extension. 9 patients (2%) had metastases (7 to the liver, 1 to the lungs and 1 to the lungs and bones). The study of the patients residence and work did not show any environmental risk factor. The initial treatment was protontherapy in 251 patients (63%), plaque therapy in 91 (23%), enucleation in 40 (10%), and other methods in 18. CONCLUSION: This was the first epidemiologic study conducted in France on this subject. It describes the clinical features of the disease, its geographical display and its management in this country.

RESUMEN

The authors present a study of 1,383 cases of invasive carcinoma of the cervix treated exclusively by radiotherapy between 1970 and 1981. Combination external radiotherapy followed by intra-cavitary applications was carried out. The study was carried out in 9 different radiotherapy centres in France using the same protocol and the same recording systems. The therapeutic results which have been recorded at every stage are among the best obtained until now, with 90% success for stage I after 5 years, 80% success for stage II, 52% for stage III growths. Only 2.1% failures occurred in the cervico-vaginal region. Pelvic recurrences were 7% in stage I and IIA, 14% in stage IIB and 24% in stage III. These recurrence rates are lower than have generally been recorded. Complication rates are also low and became less as the study continued, thanks to better use of dose distribution in individual cases which took note of doses received by neighbouring organs. The prognostic value of lymphography was analysed.

RESUMEN

OBJECTIVES: To evaluate the efficacy and morbidity of surgical treatment of carcinoma of the penis. This series of patients was derived from a retrospective multicentre study (1959-1989), initially concerning 506 patients, all treatments combined. METHODS: One hundred and sixty-eight patients treated by surgery or surgery followed by external radiotherapy between 1959 to 1989 were included. The mean follow-up is 14.4 years and the mean participation is 4.7 years. Total or partial amputation was performed as first-line treatment in 89 patients (53%) and as second-line treatment in 11 patients (7%). Thirty-two patients received external radiotherapy as a complement to surgery. Inguinal lymph node dissection was performed as first-line treatment in 68 patients (41%) and secondarily in 19 patients (11%). Postoperative inguinal radiotherapy was performed in 52 patients. Monofactorial statistical analysis of prognostic factors is proposed. RESULTS: The 5-year local control rate was 84%; it was independent of the stage of the tumour; the survival of the patients dying from any cause was 53%, the progression-free survival was 69% and the survival of patients dying from cancer of the penis was 75%. The vital prognosis is statistically significant related to the lymph node status. No significant relationship was observed between lymph node status and tumour stage. 61 complications involving the penis were observed in 40 patients (24%). Thirty-seven patients developed complications secondary to the lymph node dissection (24 cases of oedema of the lower limbs and 13 cases of inguinal sclerosis). CONCLUSION: Surgical treatment ensured a local control globally comparable to that obtained with brachytherapy, but unlike this technique, the local control is independent of the stage. Brachytherapy should not always be performed in favour of mutilation for advanced tumours because the iatrogenic effects of brachytherapy are increased in these cases. An approach to the treatment of lymph nodes is proposed based on the authors' experience and the data of the literature.
