[Preliminary results of studying the effectiveness of hemosorption in the complex treatment of children with lupus nephritis].

Hemosorption was employed in multi-modality treatment of 12 children aged 10-15 years with lupus nephritis. Of these, 5 patients suffered from nephritis associated with the nephrotic syndrome (NS), 4 patients had active pronounced nephritis without the NS, and 3 patients presented with latent nephritis. One case was characterized by transitory renal failure in the acute phase while 3 cases by chronic renal failure. Hemosorption produced a beneficial effect on the renal process and on electrolyte balance. The long-term observation over the patients evidences a short-term effect of hemosorption. After the attainment of that effect the further disease course depended on the adequacy of the conservative therapy administered to the patients with lupus nephritis.

C. parvum clinical protocols: prototypes and summary results in U. S. trials with Wellcome Coparvax.

Clinical investigations utilizing Wellcome C. parvum in cancer therapy number more than one hundred in multiple institutions. Multiple diseases in various stages are being attacked by multi-modality therapy, making the role of immunotherapy very difficult to assess. Fundamental laboratory observations have suggested ways of weaving non-specific with specific immunotherapy, and these with chemotherapy and radiation to yield maximum therapeutic benefit. Current protocols include examples of the critical interactions as well as instructive information on dosing, timing and adjunctive symptomatic therapies. Several protocols will be reviewed, especially where promising clinical results are expected. Important differences between systemic and regional administration are observed.

Adolescence and its discontents: attentional disorders among teenagers and young adults.

Attention deficit disorder (ADD) is the most commonly diagnosed childhood behavioral condition in the United States. This condition has important implications for and influences on adolescent development and adult functioning including emotional and conduct disorders, poor socialization, and school underachievement. In addition it has only been appreciated recently that some symptoms of ADD persist and can be identified among adolescents and young adults. In some situations, ADD may be newly identified during adolescence. Similar to younger children with ADD, a multi-modality approach to the management of adolescents with ADD is recommended.

Influence of varied stimuli on development of motor patterns in the premature infant.

The premature infant is at risk for both mortality and morbidity. His writhing contributes to weight loss, and his extrauterine environment does not contain the multi-modality patterned afferent stimuli that impinge upon the developing brain in utero. Sound is the most effective modality to achieve concurrent decrement in motility along with enhancement of cortical activity. It was anticipated that subjects exposed to 5 minutes of patterned sound 6 times a day would, by 36 weeks gestation, evidence: (a) less gross motor activity, (b) the normal predominance of upper over lower limb activity, and (c) beginning laterality. The sample consisted of 80 males and 73 females whose gestational age at birth was 26--33 weeks. By random assignment 52 subjects were exposed to the routine ambient noise of the isolette and nursery, 50 to a tape recording of their mother's voice, and 51 to an orchestral arrangement of Brahm's Lullaby. Limb activity was measured just prior to discharge by accelerometers worn unilaterally for a 24-hour period on the ankle and wrist prior to transfer to the alternate side for an additional 24 hours. No statistically significant differences were demonstrated among the limb patterns of the 3 groups. Large intragroup variation in gross activity precluded demonstration of between-group differences. The majority of subjects evidenced predominance of upper limb activity and laterality.

[A study on 333 patients with adenocarcinoma of the endometrium treated by combined surgery and radiation therapy (author's transl)].

Three hundred and thirty-three consecutive patients with adenocarcinoma of the endometrium treated from 1958 to 1978 by combined surgery and radiation therapy or radiation therapy alone were reviewed. According to the FIGO staging system, there were 204 stage I, 40 stage II, 24 stage III and 20 stage IV. 40 cases of recurrences were also included in this study. The main parameters influencing survival were clinical staging, depth of myometrial invasion, histologic differentiation as well as the possibilities of radical surgery in these patients. Analysis of therapeutic results shows the superiority of pre-operative intra-cavitary irradiation followed by total abdominal hysterectomy and bilateral salpingo-oophorectomy with an 80% actuarial survival at five years in stage I. Primary surgery followed by radiation therapy gives inferior results, particularly in stage II. Treatment by radiation therapy alone should be reserved for inoperable patients after careful evaluation and gives a 35% actuarial survival at five years. The incidence of serious therapeutic complications was 3,6 %. The early diagnosis of endometrial carcinoma by means of systematic endo-uterine explorations in post-menopausal bleeding and the elaboration of combined multi-modality protocol prior to any treatment should lead to a better cure rate for this cancer of increasing incidence.

A clinical statistical study of lung cancer patients in Japan with special reference to the staging system of TNM classification: a report from the Japan Joint Committee of Lung Cancer associated with the TNM System of Clinical Classification (UICC).

In 1978, after having conducted clinical field trials, the TNM Committee of Union Internationale Contre le Cancer (UICC) decided on an uniform system for the classification of lung cancer. The Japan Joint Committee of Lung Cancer (JCC) has continued to conduct field studies recommended by UICC, and since then has completed its third series carried out at 149 participating institutions. In this third series, the case records of 4,931 lung cancer patients were submitted for analysis. A clinical staging system of these findings was then set up, arranged in the TNM classification. As a result of this work, some improvements were made in the staging system. And JCC will now propose these changes, given as follows, to UICC for consideration: Occult Cancer: TX N0 M0 Stage I: T1 N0 M0, T2 N0 M0 Stage II: T0 N1 M0, T1 N1 M0, T2 N1 M0 Stage III: T3 N0 M0, T3 N1 M0, Any T N2 M0 Stage IV: Any T, Any N M1 The factors influencing the prognosis of patients with lung cancer (Yoshimura et al., 1982 (b)) (which include age, sex, histological type, modality of treatment and type of clinical staging used) were then re-evaluated. The results of this evaluation suggest an improved 5-year survival rate when using multi-modality treatment.

[Concept of therapeutic ratio by combination of radiotherapy and chemotherapy].

In combined application of radiation and drugs, the maximum therapeutic ratio should be accomplished by effective combination of the following various means. 1. Effective combination from the aspect of cell kinetics. 2. Application of hypoxic sensitizer or PLDR-inhibitor to cells of the resting phase that are resistant to radiation and chemotherapy. 3. improvement of the method of anti-cancer drug administration. 4. Reasonable planning of the intervals of radiation and chemotherapy. In solid tumors, the proportion of proliferating phase decreases with the increase in the tumor size. Anti-cancer drugs are usually effective to cells of the proliferating phase only, and cells of the resting phase are resistant to radiation. This indicates the absolute necessity of multi-modal treatment including surgical management.

The place of surgery in the treatment of ovarian cancer.

If the role of surgery has receded somewhat in other areas of gynaecological cancer, the reverse would seem to be true in ovarian cancer. The problem of the scope for increased surgical procedures outside the general run of gynaecological operations is high-lighted by the difficulty in achieving accurate preoperative diagnosis. Carcinoma of the ovary may well be found unexpectedly by the relatively inexperienced surgeon operating for a tumour presumed to be a fibroid uterus. Improvement in the survival of patients treated for cancer is only rarely the result of a single therapeutic advance. Generally it is achieved by the meticulous and individual application of multi-modal therapy. In this context careful and occasionally bold surgery remains a key treatment in the management of ovarian cancer.

[Current perspectives in the treatment of epidermoid cancer of the esophagus].

Prior to the eighties, most patients with a diagnosis of epidermoid oesophageal cancer only received palliative symptomatic care. To date, most all undergo either surgery or medical treatment or both. Late diagnosis due to lack of clinical signs in the early phases of the disease, and perhaps insufficient attempts at identifying patients at risk who could benefit from systematic screening, is still an important problem although the number of diagnosed cases continues to rise (from 104 in 1985 to 151 in 1989 in Finistere in western France). Two different therapeutic attitudes could improve the prognosis: extensive surgery as proposed by the Japonese with dissection of all invaded lymph nodes whatever the localization and a multimodal approach combining radiochemotherapy and surgery. Although outcome can apparently be improved in certain types of oesophageal cancer, the proposal of aggressive extensive dissection could have an effect on respiratory complications and would not necessarily be adapted to the risk involved in western patients. Certain teams have nevertheless taken this route and will soon report their results. In France two phase II trials combining radiotherapy, chemotherapy (cisplatinum) and surgery have reported encouraging results with complete sterilization in 24% of the cases and 50% survival at 18 months. In our own series of 68 patients, we have obtained 41% sterilization and 56.3% survival at 3 years with the multi-modal protocol. The high number of non-responders to chemotherapy emphasies the importance of maintaining surgical resection whenever possible. The discouraging reports published before 1980 have been contradicted by improvements in outcome achieved over the last decade. Today, all patients with a diagnosis of epidermoid cancer of the oesophagus should benefit from either palliative or curative care based on the latest advances in radiotherapy, chemotherapy and surgery.

[Treatment of breast cancer with ipsilateral supraclavicular node metastases].

During 1954-1977, among 2803 cases of breast cancer 99 (3.5%) had ipsilateral supraclavicular node mestastases. The results of treatment are reported, based on follow-up for more than 10 years. According to the treatment modality, the patients were divided into 4 groups: I. surgery with postoperative adjuvant chemotherapy and radiation therapy; II. radiation and chemotherapy; III. chemotherapy; IV. no treatment. In group I, surgical procedures consisted of segmental mastectomy in 6; simple mastectomy in 7; modified radical mastectomy in 16; standard radical mastectomy in 12, and extended radical mastectomy in 3. The over-all five-year survival rate was 9%. It was 18% (8/44) in group I, but only 5% (1/21) in group II. None survived for 5 years in group III and group IV. The results seem to indicate that more aggressive multi-modality treatment of breast cancer with ipsilateral supraclavicular lymph node metastases is indicated to expect better survival.

[The efficacy of granisetron as a prophylactic anti-emetic agent used in conjunction with MCNU and VP16 chemotherapeutic regimens in the management of a pediatric case of hypothalamic anaplastic astrocytoma].

The management of a 12-year-old boy with hypothalamic anaplastic astrocytoma is reported herein. The pediatric patient underwent a subtotal removal of his brain tumor, and subsequently received multimodal treatment comprising radiotherapy (30.6 Gy to the whole brain and 50.4 Gy to the local lesion) and immunochemotherapy with MCNU (80 mg/m2, day 1), VP 16 (50 mg/day, days 2 to 6), and interferon-beta (3 x 10(6) units/day, initiating on day 2 for 4 weeks). The immunochemotherapy was given as of 4 weeks after radiotherapy. The administration of anti-cancer drugs caused severe nausea and vomiting, the intra-carotid infusion of MCNU being particularly emetogenic. The multi-modal treatment was then discontinued for a few weeks. A partial response was obtained, and the patient subsequently received 3 courses of maintenance therapy at six-month intervals using the same protocol as for the initial immunochemotherapy. During maintenance therapy, granisetron (40 micrograms/kg) was given intravenously 30 minutes before and one day after the injection of MCNU. Owing to the anti-emetic management of this patient, there were no complications throughout the chemotherapy. The patient has now survived for more than 3 years with a good quality of life, showing a Karnofsky performance score of 90.

The associated targets methodology and the multi-isocenters radiosurgery treatment planning system Artemis-3D.

A new radiosurgical methodology, the "associated targets methodology" has been developed and tested by our group for the irradiation of complex cerebral arteriovenous malformations using our treatment planning system Artemis-3D. For the treatment of the arteriovenous malformations we used 15 MV photons generated by a Saturne 43 Linac, eight additional collimators (6-20 mm in diameter), the Betti fixation seat and the Talairach stereotactic frame. The successive steps of the associated targets' methodology are: -the prescription of a peripheral minimal therapeutic effective dose corresponding to the 60-70% cumulated isodose range; -the compartmentalization of the target volume into several sub-volumes, each of them having its own isocenter, collimator, irradiation space and isocenter dose weight; -the 3-dimensional computation and graphics requirements, and dose volume analysis; -the optimization evaluation criteria taking into account the dose inside and outside of the lesion. Two treatment planning software versions of Artemis-3D exist; the first one was developed for the sitting position and later for the supine treatment position, the second version is a multi-modalities imagery radiosurgical treatment planning system based on more powerful computers. Different types of stereotactic frames have been integrated. Three-dimensional visualization, stereotactic CT imaging, and angiography can be used for the sitting or supine position. We started using this methodology in 1990, and treated 44 patients during that year. For 26 single isocenter arteriovenous malformations, the obliteration rate was 22/26 (85%). In the 18 multi-isocenters irradiation cases, the overall obliteration rate was 11/18 = 61%. An example of successfully irradiated complex arteriovenous malformation is discussed to illustrate the methodology. With this three-dimensional methodology we have improved the results obtained during the first period (1986 to 1989) of our radiosurgical practice in which we used a two dimensional planification approach.

Lymph node metastasis and surgical management of gastric cancer invading the esophagus.

In 88 resected patients with esophagus-invading gastric cancer, the factors determining the prognosis of this disease were investigated by multivariate analysis. Neither, age, sex, macroscopic type, thoracotomy, nor histological type proved to be independent prognostic factors. The presence or absence of lymph node metastasis, serosal invasion, tumor size, and the extent of esophageal invasion were found to be significant independent prognostic factors. Among lymph node metastases, involvement of para-aortic lymph nodes was especially important. The prognosis was significantly better in cases in which these nodes were carefully dissected (R4 gastrectomy), than in cases in which selected dissection was performed (R2). However, no patient with mediastinal lymph node metastasis survived for any lengthy period, and thus the mediastinal lymph nodes seemed to be nodes, the dissection of which brought little effect. Postoperative results were very poor in cases in which the extent of the esophageal invasion was 3 cm or more. These patients should be treated with multi-modal therapy such as neoadjuvant chemotherapy.

The influence of age on the management of anal cancer.

The standard treatment for anal cancer is combination chemo-radiotherapy. Management decisions such as radical chemotherapy, resective surgery for poor response or relapse are frequently modified by age-associated comorbid factors. Between 1980 and 1990, our regional cancer center serving a population of 1.8 million saw 78 patients with squamous carcinoma of the anus. We have compared patients who were younger than 65 years (n = 38) with those older than 65 years (n = 38). The mean +/- standard deviation age for the whole cohort was 65 +/- 12 years, with a ratio of 2 females to each male presenting. Fewer of the elderly age group had major surgery (26% vs. 42%) (p = 0.03), and fewer suffered no toxicity (42% vs. 26%) (p = 0.03). However, 61% of the under-65-year age group are alive disease-free vs. 26% of the elderly group (p = 0.03). Similarly, only 18% of the under-65-year group died with disease compared with 37% of the elderly group (b = 0.03). For the series as a whole, the crude mortality was 42%, with 27% dying of their disease. The stage distribution, and the amount of radiotherapy or chemotherapy administered was not age-specific, but younger patients had more surgery and suffered more toxicity, with a greater proportion remaining alive and disease-free, and fewer dying of their disease. These data suggest that a more aggressive multi-modality approach in the elderly may improve disease response and survival.

Clinical and pharmacokinetic studies of all-trans-retinoic acid in pediatric patients with cancer.

This review will summarize the rationale for pursuing investigations into the use of retinoids for pediatric patients with cancer, describe the phase I results of all-trans-retinoic acid (ATRA) in children, and discuss the results of a series of preclinical and clinical pharmacokinetic studies of ATRA. The prognosis for children with advanced stage neuroblastoma, the most common extracranial solid tumor of childhood, has remained poor despite significant increases in the intensity of multi-modality therapy. Observations that neuroblastoma has the potential in vivo to differentiate into the more mature neuronal phenotype of a ganglioneuroma or to spontaneously regress, combined with the ability of ATRA to induce differentiation of neuroblastoma cell lines in vitro, suggests that neuroblastoma may be a prime candidate for a retinoid-based approach to differentiation therapy. We previously performed a standard pediatric phase I trial of ATRA and defined the maximum tolerated dose (MTD) in children to be 60 mg/m2/day, significantly lower than the MTD in adult patients. Pharmacokinetic results revealed that the plasma half-life of ATRA was short (45 min) relative to 13-cis-RA (12-24 h), and that plasma drug exposure decreased significantly by day 28 of daily drug administration. Preclinical studies using an i.v. formulation of ATRA in a Rhesus monkey pharmacokinetic model then demonstrated that ATRA is eliminated by a capacity-limited (saturable) process. This elimination process was rapidly induced within the first week of daily i.v. ATRA administration, and suggested that an intermittent schedule of drug administration might allow for down-regulation of the elimination process. These pre-clinical studies formed the basis for investigating whether an intermittent schedule of ATRA administration would allow for repeated periods of relatively higher plasma drug concentrations. Preliminary results of two clinical trials using intermittent schedules of administration suggest that this approach may result in significantly higher plasma drug exposure over time. Plans to study the role of intermittent schedules of ATRA administration in pediatric phase II trials in patients with neuroblastoma are underway.

[Pain and convalescence after ambulatory inguinal herniotomy during local anesthesia].

Postoperative pain and convalescence following ambulatory inguinal herniotomy in local infiltration anesthesia was evaluated in this descriptive study. Sixty consecutive patients (median age 63 yr) were included. Per- and postoperative pain treatment were pre- and postoperative oral tenoxicam and methadone plus infiltration of the surgical field with up to 60 ml of 0.25% bupivacaine. Intraoperative pain intensity was slight and was treated with supplemental bupivacaine. Patients were totally relieved of pain at rest and during mobilisation in the first hours after surgery, but more than half of the patients had moderate pain from the first to the third postoperative day and still had light pain seven days after surgery. Normal daily activity was re-established five days postoperatively (median). Fifty-two patients were satisfied with the anesthesia and eight patients not satisfied due to fear of intraoperative pain. This study shows that inguinal herniotomy can be performed routinely as an outpatient procedure under local infiltration anesthesia. However, late postoperative pain was significant and should be improved with multi-modal analgesia.
