Soluble interleukin-2 receptor serum level as a predictor of locoregional control and survival for patients with head and neck carcinoma: results of a multivariate prospective study.

BACKGROUND: The diagnosis and follow-up of head and neck carcinoma patients are based exclusively on clinical staging, which cannot always predict clinical outcome accurately. Because oral squamous cell carcinomas produce interleukin (IL)-6 and tumor necrosis factor (TNF)-alpha and express IL-2 receptors, the authors assessed the prognostic value of the serum levels of these markers. METHODS: Serum levels of IL-6, TNF-alpha, soluble IL-2 receptors (s-IL-2-R), and acute phase proteins were measured at the time of diagnosis in a prospective study of 85 patients with primary squamous cell carcinoma of the head and neck. The influence of each clinical and laboratory parameter on locoregional control and survival was analyzed. RESULTS: At presentation, a relationship was observed between advanced tumor (T) classification and high serum levels of CRP (P = 0.0015) and s-IL-2-R (P < 0.05). A high lymph node (N) classification was significantly associated with elevated serum IL-6 (P = 0.01) and CRP levels (P = 0.0002). In the univariate analysis, T classification, N classification, performance status, Prognostic Inflammatory and Nutritional Index, and serum s-IL-2-R level were significantly correlated with both locoregional control and survival. Multivariate analysis showed that the only significant prognostic factors related independently to locoregional control were N classification (P = 0.02) and serum s-IL-2-R level (P = 0.02). In a Cox multivariate analysis, serum s-IL-2-R level was found to be the most predictive factor of survival (P = 0.0001). CONCLUSIONS: This study shows that serum s-IL-2-R level at the time of diagnosis represents a new independent prognostic variable for predicting the risk of locoregional recurrence and survival for patients with head and neck squamous cell carcinoma.

[Laryngeal cancer and conservative treatment. Place of combined radiotherapy chemotherapy and modified fractionation radiotherapy].

For patients with early stages of laryngeal carcinomas, the local therapeutic modalities of surgery and/or radiation are the accepted standards of treatment. Recently, combined chemotherapy-radiotherapy and new fractionation schedules have received much attention as an alternative to surgery in patients with resectable locally advanced cancer of the larynx to preserve the larynx function. This article is intended to update the reader on the most recent articles written about the treatment of laryngeal carcinomas. The different points are: the results of conventional radiotherapy, the importance of parameters of radiotherapy (dose, fractionation, overall treatment time), new fractionation schedules, combined chemo-radiotherapy, randomized trial results.

Anemia is associated with lower local-regional control and survival after radiation therapy for head and neck cancer: a prospective study.

PURPOSE: To evaluate the prognostic value of anemia in squamous cell carcinomas in the head and neck treated with curative radiation therapy alone. MATERIALS AND METHODS: In a prospective study, the hemoglobin level was measured prior to radiation therapy in 217 patients (188 [87%] men and 29 [13%] women) with cancer of the oral cavity (n = 61 [28%]), oropharynx (n = 53 [24%]), hypopharynx (n = 21 [10%]), and larynx (n = 82 [38%]). Anemia, defined as hemoglobin level below 13.5 g/dL in men and below 12.0 g/dL in women, was diagnosed in 58 (31%) of the men and five (17%) of the women. Median follow-up was 29 months (range, 2-63 months). RESULTS: The 2-year actuarial probability of local-regional control was 69% (95% confidence interval, 63%, 76%). Multivariate analysis showed the relative risk of failure of local-regional control to increase for stage T3 and T4 tumors (1.8 [95% confidence interval, 1.1, 3.1]), stage N3 nodes (3.6 [95% confidence interval, 1.8, 7.1]), weight loss (2.2 [95% confidence interval, 1.3, 4.0]), and anemia (1.6 [95% confidence interval, 1.0-2.7]). The relative risk of death increased for stage T3 and T4 tumors (2.5 [95% confidence interval, 1.4, 4.3]), N3 nodes (4.0 [95% confidence interval, 1.0, 7.9]), oral cavity tumors (2.0 [95% confidence interval, 1.2, 3.2]), male sex (4.1 [95% confidence interval, 1.3, 13.1]), weight loss (2.2 [95% confidence interval, 1.3, 3.7]), and anemia (1.7 [95% confidence interval, 1.03, 2.7]). CONCLUSION: Moderate anemia appeared to be an independent prognostic factor in squamous cell carcinoma of the head and neck treated with radiation therapy alone.

Actuarial Analysis

[Surgery of the hypopharynx after radiotherapy].

Changes in surgical procedures for hypopharynx cancer after definitive radiotherapy are important since the use of pedicled myocutanous flaps and free digestive transplants. Postoperative course is improved and salvage surgery more frequent. From 1970 to 1990, 160 hypopharyngeal carcinomas were operated on after radiotherapy, 103 due to failures or complications after definitive irradiation and 57 metachronous cancers. During this period, the rate of lethal postoperative complications decreased from 25% to 8%. Crude survival rates are 51% at 1 year, 22% at 3 years and 15% at 5 years. Poor prognostic features are local extension, positive margins and extracapsular nodal spread. Postoperative deaths and failures in primary or neck account for 60% of the causes of death. Results of salvage surgery are unsatisfactory: the choice of definitive radiotherapy with surgery in reserve must be restricted to selected cases.

[Surgery of the oropharynx after radiotherapy].

Over 40 years after the first commando procedures performed by M Dargent, surgical techniques such as mandibulotomy and myocutaneous flaps yield important changes in oropharyngeal surgery after definitive radiotherapy. Wide resections and simultaneous neck dissection are possible with good functional results. From 1970 to 1990, 250 patients with a carcinoma of the oropharynx were operated on after radiotherapy, 163 because of failure or complication of irradiation, 87 for a metachronous carcinoma occurred in an previously irradiated field. The postoperative mortality rate was 6%. The risk of carotid blow-up did not increase with the extension of the resection. Survival rates at 1, 3 and 5 years are 55%, 22%, 16% in salvage surgery and 69%, 36% and 24% in patients with metachronous cancer. Postoperative complications and failures in the primary and/or the neck account for 60% of causes of death. These results suggest that prior surgery of deeply ulcerative carcinoma of the oropharynx followed by radiotherapy is a better strategy than definitive radiotherapy with salvage surgery in reserve.

Prognostic value of tumor regression during radiotherapy for head and neck cancer: a prospective study.

OBJECTIVE: Prospective evaluation of tumor regression during external irradiation for head and neck squamous cell carcinomas and its association with long-term local control. METHODS AND MATERIALS: Two hundred twenty-eight patients with histologically confirmed squamous cell carcinoma [oral cavity: 59 (26%), oropharynx: 65 (29%), hypopharynx: 37 (16%), larynx: 67 (29%)] were included between January 1986 and December 1990. Curative intent external irradiation delivered 65-70 Gy over a period of 7 weeks (five 2 Gy fractions per week). Tumor regression was evaluated clinically and endoscopically every week. RESULTS: Tumor regression, assessed at 2 weeks, was as follows: no response: 62 (30%), 25% response: 121 (59%); 50% response: 23 (11%). At 5 weeks, 9 (4%) patients showed 0-25% regression, 75 (33%) showed 50% regression, 115 (50%) showed 75% regression, and 29 (13%) showed complete regression. Median follow-up was 79 months (range: 6-96 months). The local control probability was 68% (62-74%) at 2 years, 65% (59-70%) at 5 years. Univariate analysis showed that, at 2 weeks, local control was significantly different between the nonresponders and the patients with 25% or greater response (p < 0.025) and that, at the fifth week, local control was very different between the major responders (75 and 100%) and the minor responders (0-50%) (p < 0.0001). Multivariate analysis (Cox Proportional Hazards Model) showed that the probability of local relapse was significantly and independently increased for minor regression at 5 weeks [Relative risk (RR) of failure was 2.3 (1.4-3.7)], for nonlaryngeal tumors [RR: 2.4 (1.3-4.5)], and for Stage T3-T4 [RR:2.4 (1.4-4)]. Three prognostic groups can, therefore, be proposed: 1) low risk of recurrence when regression > or = 75% and laryngeal tumor or T1-T2 tumors in other sites: 106 (46.5%) patients, 2-year local control probability: 84% (77-92%); 2) high risk of recurrence: regression < or = 50% and T3-T4 nonlaryngeal tumors: 44 (19%) patients, 2-year local control probability: 27% (13-41%); 3) intermediate risk of recurrence: 78 (34.5%) patients, 2-year local control probability: 69% (58-80%). CONCLUSION: The present study suggests that tumor regression during external radiotherapy is an independent predictive factor of local control in head and neck carcinomas.

[Management of laryngeal cancers].

With 5,000 cases yearly, laryngeal carcinomas account in France for the third of squamous cell cancers of the upper digestive and respiratory tract. The crude survival rate is 50% at 5 years. Carcinomas of vocal cords are often diagnosed as early stages if dysphonia leads the patients to the ENT specialist within 2 weeks. Cure of the primary is achieved in 90% of the early stages by radiotherapy with narrow fields or partial surgery, with a 80% 5 years survival rate. Advanced tumors are often treated by total laryngectomy and postoperative radiotherapy. Supra-glottic cancers (epiglottis) are more serious. Unilateral dysphagia or upper cervical neck node often delay early diagnosis. A total laryngectomy is the commonest treatment. The 5 years survival rate of 40% is due to local and/or regional failures and metachronous cancers in head and neck, and radiotherapy remains the two major treatments. Primary prevention is based upon suppression of tobacco and reduction of alcoholic consumption, secondary prevention on resection of leucoplakia and close follow-up of patients with chronic laryngitis.

Is reseeding from the primary a plausible cause of node failure?

In a previous analysis of node failures in 1251 consecutive patients with node positive oropharyngeal and pharyngolaryngeal squamous cell carcinomas treated by external radiotherapy alone at the Institut Curie, the main reasons for patient exclusion were node recurrence associated with primary failure (N+T failures) and doses less than 55 Gy. These exclusions reduced the number of node failures from 399/1251 (32%) to 77/798 (10%). Multivariate analysis of node recurrence indicated that node size and fixity, treatment duration, and T stage of primary were significant (higher probability of isolated node failure for the T1-T2 primaries). In the present analysis, it is noted that 60% of the N+T failures were observed less than 1 month after the completion of the irradiation and, therefore, were not likely the result of reseeding from the primary tumor. When all 1251 patients were included in the analysis, the probability of nodal failure increased for larger nodes, T4 primaries, lower nodal doses, presence of contralateral node metastases, and nodal fixation to the surrounding structures. No influence of the primary site was found. Treatment duration was closely associated with total dose to the nodes. The best description of the data was obtained with a model including total dose and not treatment time. However, as in the previous analysis, the exclusion of low-dose (less than 55 Gy) treatments resulted in the loss of a significant dose-control relationship. We conclude that the majority of node failures is unlikely to result from reseeding from the primary tumor, and therefore should not be excluded from local-control analyses. From a more radiobiological point of view, the exclusion of palliative treatments is questionable when studying the effect of dose on local control.

Induction chemotherapy in advanced head and neck tumors: results of two randomized trials.

From March 1983 to December 1989, 208 patients with locally advanced squamous cell carcinoma of the head and neck were successively included into two randomized induction chemotherapy trials. The chemotherapy regimen of the first trial, which included 100 patients, consisted of two cycles of a combination of cisplatin, bleomycin, vindesine and mitomycin C; while that of the second trial, which included 108 patients, consisted of three cycles of a combination cisplatin, 5-fluorouracil by continuous infusion and vindesine. Local treatment was the same in the two trials: primary radiotherapy in all patients. The response was then evaluated; in the case of a poor response at 55 Grays surgery was performed; otherwise, radiotherapy was continued to full doses (possibly followed by salvage surgery). The tumor and lymph node responses to chemotherapy (complete and partial response) were higher in the second trial than in the first: 70% versus 50% for primary lesions, 47% versus 25% for lymph nodes. The toxicity of the two chemotherapy regimens was minimal. In the two trials, an initial major response to chemotherapy predicted subsequent efficacy of irradiation in 80% of the patients. The significance of the complete response at the end of the irradiation varies with the previous response to the chemotherapy. With a median follow-up of 60 months with the first chemotherapy regimen and 30 months with the second, overall survival and disease-free interval were very similar in the two groups. The incidence of distant metastasis was significantly reduced (p less than 0.03) with chemotherapy. This trial suggests the need to test new chemotherapy protocols according to new schemes of treatment, with chemotherapy given concurrently with or following the completion of standard treatment by means of multicenter randomized trials.

[Role of neoadjuvant chemotherapy in the treatment of advanced head and neck tumors. Results of two randomized therapeutical trials conducted at the Institut Curie on 208 patients].

From March 1983 to December 1989, 208 patients with locally advanced squamous cell carcinoma of the head and neck were successively included into two trials randomizing induction chemotherapy versus no pre-irradiation treatment. The chemotherapy regimen of the first trial, which included 100 patients, consisted of two cycles of a combination of cisplatin, bleomycin, vindesine, mitomycin C; while that of the second trial, which included 108 patients, consisted of three cycles of a combination cisplatin, 5-fluorouracil (continuous infusion) and vindesine. Local treatment was the same in two trials: 'primary' radiotherapy in all patients. The response was then evaluated at 55 Gy; in the case of poor response, surgery was performed, otherwise radiotherapy was continued to full doses (possibly followed by salvage surgery). The tumor and lymph node responses to chemotherapy (complete and partial response) were higher in the second trial and in the first one: 70% versus 50% for primary lesions, 47% versus 25% for lymph nodes. The toxicity of the two chemotherapy regimens was minimal. In the two trials, an initial major response to chemotherapy predicted subsequent efficacy of irradiation in 80% of the patients. Complete response rate at the end of irradiation correlates with the previous response to the chemotherapy. With a median follow-up of 60 months with the first chemotherapy regimen and 30 months with the second, overall survival and disease-free interval did not significantly differ in the two groups of patients, with or without chemotherapy. The incidence of distant metastasis was significantly reduced (P < 0.03) in the chemotherapy arms. This negative trial encourages the design of new chemotherapy protocols according to new schemes of treatment. For advanced stages of head and neck cancers (T3, T4, N2, N3), we recently launched a pilot study combining platinum and irradiation, but according to a concomitant schedule.

Results of radiation therapy in carcinoma of the base of the tongue. The Curie Institute experience with about 166 cases.

Between 1960 and 1980, 166 patients with squamous cell carcinoma of the base of the tongue were treated with primary irradiation at the Curie Institute (Paris, France). Distribution according to the TNM system 1978 International Union Against Cancer (UICC) was the following: 22 T1 lesions, 47 T2 lesions, 64 T3 lesions, and 33 T4 lesions. Regional nodes were not palpable in 50 cases, 35 had N1 nodes, 12 had N2 nodes, and 69 had N3 nodes. All patients received external beam radiation. The 2-year, 3-year, and 5-year overall survival rates for all patients were, respectively, 45%, 37%, and 27%. Local control was significantly related to the initial status of the primary, to the tumor regression at the end of the radiation therapy, and to the histologic differentiation. The 2-year local control was 96% for T1 lesions, 57% for T2 lesions, 45% for T3 lesions, and 23% for T4 lesions. Local control was 70% if the tumor regression was complete at the end of the treatment and 27% if the tumor regression was partial. No significant differences were found in primary local control with respect to degree of infiltration, age, and dose of radiation therapy over a dose of 60 Gy in 6 weeks. The 3-year regional control was 86% for N0, 78% for N1, and 60% for N2 and N3. Among the tumor characteristics analyzed, the most useful ones for predicting local control and survival were clinical tumor staging parameters and tumor radiation-induced regression. A new therapeutic approach based on the evaluation of the tumor regression at 50/55 Gy is under discussion.

Impact of cervical disease and its definitive radiotherapeutic management on survival: experience in 2013 patients with squamous cell carcinomas of the oropharynx and pharyngolarynx.

Two thousand thirteen patients with squamous cell carcinoma of oropharynx and pharyngolarynx were reviewed with regard to neck disease presentation and disease-free survival after radical radiotherapy. All patients were staged according to both the AJCC 1976 and the UICC 1978 classifications. Causes of failure, disease-free survival, and complication rates were assessed. Sixty percent had a clinically positive neck. The 3-year disease-free survival rates were 58%, 44%, 38%, and 25% for AJCC N0, N1, N2, and N3 cases, respectively. Corresponding UICC figures were 58%, 46%, 26%, and 29%. Analyzed parameters were nodal stage, size, site and fixity, and location of primary. Complications attributed to neck disease did not exceed 3%. A critical appraisal of the nodal staging systems is derived from these sets of data.

Conventional megavoltage radiotherapy in the management of malignant epithelial tumours of the parotid gland.

This is an evaluation of definitive conventional megavoltage radiotherapy in a consecutive series of 35 patients presenting malignant epithelial tumours of the parotid gland. In this series, the 5-year actuarial locoregional control rate was 41% with a 5-year crude survival rate of 36%. The results are analyzed according to tumour presentation and tumour doses. Six of 15 patients with tumours larger than 6 cm have had a lasting locoregional control. During the same period 43 other patients received radiotherapy as a post-operative modality. Results obtained in this group confirm the previously published data. While recent studies tend to demonstrate the specific efficacy of high LET radiation in the management of locally advanced salivary gland tumours, radical conventional radiotherapy can still be employed with a curative intent when neutron facilities are not available.

A multivariate primary tumour control analysis in 465 patients treated by radical radiotherapy for cancer of the tonsillar region: clinical and treatment parameters as prognostic factors.

Out of a consecutive series of 698 cases of squamous cell carcinomas of the tonsillar region treated by radical megavoltage radiotherapy, a determinate group of 465 cases remained eligible for a multivariate analysis of the pretreatment features of the disease and treatment-related parameters predictive of lasting control of the disease at the primary site. T-stage and initial site within the tonsillar region, were the significant pretreatment factors. Tumours arising from the glossopalatine sulcus which are characterized by involvement of the tongue, do significantly worse than those arising from other sites within the tonsillar region: i.e. the tonsil itself, posterior pillar and to a lesser extent the anterior pillar. As regards treatment-related parameters in the 465 cases which received tumour doses of at least 55 Gy, only the length of overall treatment time was found to be predictive. Combining both pretreatment and treatment variables, T-stage (p less than 0.0001), overall treatment time (p less than 0.0001) were by decreasing order of significance the predicting factors, followed by initial site (p = 0.006). When present, tumour extension to the anatomical structures anterior to the tonsillar region was also found to be significant (p = 0.05). Based on these factors, a multivariate model was constructed and tested by estimating the product-limit survival of the various categories of patients. Four groups are individualized with 3 years local control rates ranging from 90 to 21%. The predictive accuracy of the model was assessed by log-rank test significance levels. The model may help to select patients for whom conventional radical radiotherapy is inadequate, and combined modality or altered fractionation regimes should be tried particularly for advanced tumours of the glossopalatine sulcus, and any case with significant invasion of the oral cavity.

Induction chemotherapy in advanced head and neck cancer. Preliminary results of a randomized study.

From March 1983 to June 1986, 100 patients with locally advanced squamous cell carcinoma of the head and neck were randomized to receive either two courses of chemotherapy prior to local therapy (group A), or local therapy alone (group B). Local treatment consisted of primary radiotherapy in all patients. When a poor response was observed after 55 Gy, surgery was performed. The chemotherapy regimen was a combination of cisplatinum, bleomycin, vindesine, and mitomycin C. The response rate to induction chemotherapy (group A) was 50% for the primary tumor (CR: 10% and PR: 40%). At the end of radiotherapy, the overall tumor response rates in the two groups A and B, were 77% and 79% respectively. Complete disappearance of the primary tumor occurred more often than that of the lymph node metastases. The response rate to induction chemotherapy for lymph node metastases was 27.1% (CR: 9% and PR: 18.1%). An initial major response to chemotherapy predicted subsequent efficacy of irradiation on 90% of the cases, while a failure of chemotherapy had no predictive value in this respect. The survival rates in groups A and B were 66.5% vs. 65.1% at 1 year and 35% vs. 46.2% at 2 years. Local disease-free and disease-free intervals were similar in both groups. A Cox's multi-step regression analysis revealed two significant independant prognostic factors: size of primary tumor and nodal status. After adjustment for these factors, the chemotherapy did not seem to improve the effectiveness of the local treatment in terms of loco-regional control and survival.

Results of irradiation in squamous cell carcinoma of the soft palate and uvula.

Out of a series of 235 patients presenting with tumours of the soft palate at the Institut Curie, between 1958 and 1980, 146 cases were analysed to evaluate the results of radical radiation therapy. Seventy patients (48%) had advanced T3-T4 disease and 40 patients (27%) had clinically involved metastatic nodes. All patients had a minimum follow-up of 5 years. In 103 cases, megavoltage X-ray therapy was employed. For 43 patients, presenting with small or moderately advanced tumours, a combination of megavoltage and intra-oral orthovoltage X-rays was used. The local control rate at 3 years was 92% for T1, 70% for T2, 58% for T3 and 49% for T4 lesions. Nodal failure was seen in 19 patients. In 9 of these, it was not associated with failure at the primary site, 7 out of 9 occurring marginally or outside the treatment portals. Complications were observed in 16 patients, 7 requiring surgery. The crude 3 and 5 year survival rate was 52 and 40%, respectively, and the disease-free survival 59 and 53%.

Primary radiotherapy of squamous cell carcinoma of the oropharynx and pharyngolarynx: tentative multivariate modelling system to predict the radiocurability of neck nodes.

In a series of 1251 cases of squamous cell carcinomas of oropharynx and pharyngolarynx with clinically positive neck and treated primarily by radiation therapy a determinate group of 798 cases remained eligible for a multivariate analysis of the prognostic factors related to the regional outcome. Node size (p less than 0.0001), node fixity (p = 0.016) and T stage (p = 0.02) were the significant pretreatment factors independently predictive of neck node control. when regarding the treatment modalities in this determinate group of patients who received tumor doses of at least 55 Gy, only the treatment duration was found to be predictive (p = 0.002). Based on these factors, a multivariate model was constructed and tested by estimating the product-limit survival of the various groups of patients. The predictive accuracy of the equation was assessed by the log-rank test significance levels. The model may help to select, in many clinical situations, the appropriate approach of the management of metastatic neck disease, either by definitive radiation therapy or by combined modalities.
