The outcome of limited field irradiation for medically inoperable patients with peripheral stage I non-small cell lung cancer (NSCLC) was analyzed to discuss the elective irradiation of regional lymph nodes. From 1976 through 1994, 36 patients with peripheral stage I NSCLC were treated with definitive radiation therapy (RT) alone at Gunma University hospital. The total dose ranged from 60 to 81 Gy with a 2 Gy-daily standard fractionation, although only one patient received 48 Gy. Ten patients received elective irradiation of the regional lymph nodes with a total dose of 40 Gy or more. The overall response rate was 97% with 31% complete responses. The overall survival rates at 3 and 5 years were 42 and 23%, and disease-specific survival rates were 56 and 39% at 3 and 5 years, respectively. In 26 patients without the elective regional irradiation, disease-specific survival rates at 3 and 5 years were 53 and 40%, respectively, whereas they were 64 and 39% in 10 patients with the regional nodal irradiation. The cumulative 5-year local progression rate was 28%, and the overall progression rate was 60% at 5 years. Four patients had a local recurrence as the only site of initial tumor progression. Combined local and regional progression was seen in two patients, and one patient had a local recurrence in combination with distant metastasis. Twelve patients had distant failure without evidence of local or regional progression. Only one patient without regional nodal irradiation developed an isolated regional failure. No patient had serious complications related to RT. High-dose limited field RT is justified for medically inoperable patients with peripheral stage I NSCLC. The regional nodal irradiation can be omitted in these pulmonary compromised patients because of the low regional relapse rate. Dose-escalation by a conformal RT with a small target volume can be expected to provide a better local control rate and better survival. The objective of this study was to determine whether the addition of concurrent 5-fluorouracil (5-FU) and/or a change in radiation fractionation improves pelvic control and survival or decreases complications in advanced cervical cancer, FIGO stages IB/IIA (>=5 cm) to IVA inclusive. After stratification by pelvic disease extent, 234 of a planned 292 patients were randomized to receive one of four possible treatments: (a) standard external beam pelvic irradiation (RT) 5000 cGy in 25 fractions versus (b) RT as in arm (a) with infusional IV 5-FU 1g/m2 daily in the first and last 4 days of RT, (c) partially hyperfractionated RT, 5280 cGy in 33 fractions, two fractions per day on the first and last 4 days of RT, or (d) arm (c) with the same FU. All were followed with a linear source of intracavitary RT to deliver 40 Gy. The median duration of follow-up for the 221 evaluable patients was 59 months. The 5-year Kaplan-Meier disease-free survival (DFS) in arm (a), (c), (d), and (b), respectively, were 45, 53, 58, and 61%. The differences in survival and pelvic control were not statistically significant. An exploratory subset analysis was performed within stratum 1 and stratum 2 to generate hypotheses for future studies. Only for the 99 patients in stratum 1 (IB/IIA or medial parametrial IIB disease) was the 5-year DFS significantly better (long rank P = 0.05) for standard RT and 5-FU. The DFS was 39% for arm (a), 76% for arm (b), 58% for arm (c), and 65% for arm (d). A multivariate analysis of patient, tumor, and treatment related prognostic factors identified only the use of 5-FU to account for the observed difference. The crude serious late bowel or bladder complication rate was 5.9%. Overall concurrent infusional 5-FU was not beneficial when added to standard RT in this study. The possible benefit for patients in stratum 1 requires exploration in a further randomized trial with appropriate accrual.

                Between 1980 and 1990, 71 patients treated at MDACC by radiation therapy alone for NSCLC because of medical contradindications for surgery were analyzed. All patients had histologic or cytologic confirmation of NSCLC. The median total radiation dose was 63.23 Gy with 79% of patients receiving doses exceeding 60 Gy. The radiographic response was documented at completion of radiation therapy and 6 months after completion of radiation therapy. The median follow-up time was 36 months, ranging from 14-61 months.
                Overall survival rates at 3 and 5 years were 19 and 12%, respectively. The disease-specific survival (DSS) rates at 3 and 5 years were 44 and 32%, respectively. The DSS rates at 3 years by T-stage were: 49% for T1, 47% for T2, 26% for T3, and 32% for T4. The local control rates at 3 and 5 years were 66 and 56%, respectively. The local control rates at 3 years by T-stage were: 89% for T1, 61% for T2, 42% for T3, and 55% for T4. Univariately, the significant favorable prognostic factors for DSS were a KPS > or = 70, tumor size < or = 5 cm, no chest-wall invasion, and a radiation dose > or = 50 Gy. The significant favorable prognostic factors for local control were tumor size < or = 4 cm, no chest-wall invasion, a radiation dose > 60 Gy, and a complete response confirmed by chest x-ray at 6 months after radiotherapy (p = 0.04). Coverage of nodal drainage areas did not affect survival or local control. No lethal complications were seen, and documented symptomatic radiation pneumonitis occurred in only 7% of cases. Hence, the significant favorable prognostic factors for DSS were a KPS of > or = 70, tumor size < or = 5 cm, no chest-wall invasion, and a radiation dose > or = 50 Gy. The significant favorable prognostic factors for local control were tumor size of < or = 4 cm, no chest-wall invasion, a radiation dose > 60 Gy, and a complete response confirmed by chest x-ray at 6 months after radiotherapy. Multivariate analysis showed that the most important prognostic factor for DSS was KPS, and the most important prognostic factor for local control was radiation dose.
                Patients with a KPS of > or = 70, a tumor size < 5 cm, and no chest-wall invasion would benefit most from treatment with radiation alone to doses exceeding 60 Gy. This patient group represents the best sample for studying the benefit of conformal radiotherapy. To determine whether, in the postoperative setting, accelerated fractionation (AF) radiotherapy (RT) yields a superior locoregional control rate compared with conventional fractionation (CF) RT in locally advanced squamous cell carcinomas of the oral cavity, oropharynx, larynx, or hypopharynx.
                Patients from four institutions with one or more high-risk features (pT4, positive resection margins, pN >1, perineural/lymphovascular invasion, extracapsular extension, subglottic extension) after surgery were randomly assigned to either RT with one daily session of 2 Gy up to 60 Gy in 6 weeks or AF. Accelerated fractionation consisted of a "biphasic concomitant boost" schedule, with the boost delivered during the first and last weeks of treatment, to deliver 64 Gy in 5 weeks. Informed consent was obtained. The primary endpoint of the study was locoregional control. Analysis was on an intention-to-treat basis.
                From March 1994 to August 2000, 226 patients were randomized. At a median follow-up of 30.6 months (range, 0-110 months), 2-year locoregional control estimates were 80% +/- 4% for CF and 78% +/- 5% for AF (p = 0.52), and 2-year overall survival estimates were 67% +/- 5% for CF and 64% +/- 5% for AF (p = 0.84). The lack of difference in outcome between the two treatment arms was confirmed by multivariate analysis. However, interaction analysis with median values as cut-offs showed a trend for improved locoregional control for those patients who had a delay in starting RT and who were treated with AF compared with those with a similar delay but who were treated with CF (hazard ratio = 0.5, 95% confidence interval 0.2-1.1). Fifty percent of patients treated with AF developed confluent mucositis, compared with only 27% of those treated with CF (p = 0.006). However, mucositis duration was not different between arms. Although preliminary, actuarial Grade 3+ late toxicity estimates at 2 years were 18% +/- 4% and 27% +/- 6% for CF and AF, respectively (p = 0.10).
                Accelerated fractionation does not seem to be worthwhile for squamous cell carcinoma of the head and neck after resection; however, AF might be an option for patients who delay starting RT. A prospective, randomized Phase Ilate/II trial of hyperfractionated radiation therapy was conducted: 1.2 Gy minimum tumor dose was administered twice daily with a minimum interval of 4 hr, 5 days per week. Patients with Stage III and IV carcinomas of the oral cavity, oropharynx, nasopharynx, hypopharynx, and supraglottic larynx were stratified by site, presence or absence of nodal metastases, and performance status. They were assigned to four total doses between 67.2 Gy and 81.6 Gy to all known tumors. The highest dose arm was opened after preliminary assessment indicated acceptable late morbidity rates with the three lower doses. Of 479 patients entered, 260 patients were randomized to the three lower total doses and 237 were analyzed for this preliminary report: 63 were assigned to receive 67.2 Gy, 58 to 72.0 Gy, and 116 to 76.8 Gy. Estimates of grade 4 necrosis at 2 years were 10.0%, 5.1%, and 13.9%, respectively, for patients who received total doses of 67.2 Gy, 72.0 Gy, and 76.8 Gy. There was a suggestion of a trend toward increased local control at 24 months (Kaplan-Meier estimates of 25% for 67.2 Gy, 37% for 72.0 Gy, and 42% for 76.8 Gy) (p = .08). No difference was observed in survival. Assessment of the results using Cox regression models to correct for slight inequalities of pretreatment prognostic variables supported a total dose-tumor control relationship (p = .054). Results for the lowest dose arm were comparable to previous RTOG studies of common fractionation with similar total doses. The higher local control rates with 72.0 and 76.8 Gy using hyperfractionated radiation therapy suggest an improvement in outcome with radiation therapy for advanced carcinomas of the upper aerodigestive tracts. These preliminary findings have led to a Phase III comparison of hyperfractionated radiation therapy with 1.2 Gy b.i.d. with standard fractionation. To evaluate if the timing of chest irradiation with respect to chemotherapy would influence survival and local and distant control in patients with limited-stage small-cell lung cancer (LSCLC).
                From 1981 to 1989, 199 consecutive patients with LSCLC were randomly allocated to receive initial chest irradiation (ICI; n = 99) or late chest irradiation (LCI; n = 100) given 18 weeks delayed. Both groups received the same nine cycles of combination chemotherapy: three cycles of cisplatin and etoposide and six cycles of cyclophosphamide, doxorubicin, and vincristine. In the first part of the study, prophylactic cranial irradiation (PCI) was only given to patients randomized to ICI, but after inclusion of 42 patients in the LCI arm, the protocol was changed, so that all patients received PCI independent of the timing of the chest irradiation (CI). A total of 157 patients received PCI with a radiation dose of 25 Gy in 11 fractions.
                The timing of radiotherapy had no significant effect on the 2-year overall survival rate (20% after ICI v 19% after LCI, P = .4) or the 2-year in-field recurrence rate (72% after ICI v 68% after LCI, P = .2). Median survival durations were 10.5 (ICI) and 12.0 (LCI) months. Similarly, no difference in the 2-year incidence of CNS recurrences was found between the 2 arms in patients who received PCI (19% after ICI v 13% after LCI, P = .24). Bone marrow toxicity was acceptable, as 15% developed World Health Organization (WHO) grade 4 leukocytopenia and 4% grade 4 thrombocytopenia. Grade 4 leukocytopenia was more pronounced in the ICI group. There was no difference in the frequency and severity of other toxicities between the 2 groups.
                Timing of CI did not significantly influence the incidence of in-field recurrences, CNS recurrences, or overall survival. Women with gynecological cancers have reported poor health-related quality of life (QOL), with complex physical and psychological needs post-surgery and during chemotherapy treatment. There are no studies reporting interventions addressing these needs post-hospital discharge in this population.
                Patients were randomized into two groups. The intervention group received 6 months of specialized care by an Advanced Practice Nurse (APN); in addition, women with high distress were evaluated and monitored by a psychiatric consultation-liaison nurse (PCLN). The attention control group was assisted with symptom management by a research assistant. The effects of the 6-month intervention were evaluated using self-report questionnaires at baseline (24-48 h after surgery), 1, 3, and 6 months post- surgery. QOL assessments included the Center for Epidemiological Studies-Depression Scale , the ambiguity subscale of the Mishel Uncertainty in Illness Scale , the Symptom Distress Scale, and the Short-Form Health Survey (SF-12). The sample for the longitudinal analysis included 123 who completed QOL outcome measures across three occasions post-surgery.
                The APN intervention resulted in significantly less uncertainty than the attention control intervention 6 months after surgery. When the sub-group who received the APN plus PCLN intervention was compared with the total attention control group, the sub-group had significantly less uncertainty, less symptom distress, and better SF-12 mental and physical QOL over time.
                Nurse tailored interventions that target both physical and psychological aspects of QOL in women recovering from cancer surgery and undergoing chemotherapy produce stronger outcomes than interventions that target solely one QOL aspect.
                (c) 2008 John Wiley & Sons, Ltd. The analysis of complications in a prospective randomized trial comparing two preoperative brachytherapy low-dose rates in early stage cervical cancer is presented.
                Between 1985 and 1988, 204 patients with Stage I and limited Stage II cervical cancer were randomized to receive one of two preoperative brachytherapy low-dose rates (0.4 and 0.8 Gy/hr). The objective of this trial was to determine the benefits, if any, of the higher-dose rate within the therapeutic arsenal for this patient population, in terms of survival, local control, and complications. The type and severity of all complications were evaluated according to a common glossary and a strict follow-up schedule was established given that the treatment of cervical cancer is multidisciplinary, involving gynecologists, surgeons, and radiotherapists.
                Overall survival: 85% at 2 years and local control: 93% at 2 years, were similarly distributed between the two groups. Regardless of their nature and severity, 139 and 175 complications were observed among 63% and 75% of patients, in the 0.4 and 0.8 Gy/h dose rate groups respectively. Gynecologic and urinary complications were the most frequent (38% and 28% of all complications), followed by vascular (15%), digestive (10%), nervous (5%) and cutaneous (5%). A total of 14 and 17 severe complications (Grade 3) were observed in 7% and 13% of patients, respectively in the 0.4 and 0.8 Gy/h dose rate groups (p = 0.12). Nonparametric survival methods used to compare the time to the first complication did not show a significant difference between the two groups: 62% and 72% at 2 years (p = 0.27). When the first complication and its evolution were considered (early complications), the prevalence of complications was not significantly different between the two groups: 28% vs. 34% at 2 years (p = 0.31). In this prospective trial, patients were regularly followed-up and complications of varying nature and severity were observed in succession during follow-up. When successive complications and their evolution were taken into account, the prevalence of complications was significantly greater in the higher-dose rate group: 30% vs. 45% at 2 years (p = 0.03).
                The results of this trial showed that long-term effects of treatment, when represented by prevalence of complications over time, were more frequent in the higher dose rate group. This underlines the importance of the regular follow-up of patients and of coding, not only the occurrence of all complications, but also their evolution over time. The burden of cancer care in general practice is increasing. Patient-held records may facilitate effective, coordinated care, but no randomised controlled trials of their use in cancer care have been conducted, and concerns about possible negative effects remain.
                To evaluate the use of a supplementary patient-held record in cancer care.
                Six hundred and fifty radiotherapy outpatients with any form of cancer were randomised either to hold a supplementary record or to receive normal care. It was explained to record holders that the supplementary record was intended to improve communication with health professionals and act as an aide memoire. After three months, patients' satisfaction with communication and with participation in their own care were assessed. Global health status, emotional functioning, and cognitive functioning were measured using the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire.
                There were no significant differences between groups in any of the outcome measures. Patients in both groups expressed a high level of satisfaction with communication and participation in their care. Mean (SD) scores in the intervention and control groups were: global health status, 66.8 (24.2) and 65.3 (23.7); emotional functioning, 75.0 (24.6) and 77.4 (22.8); cognitive functioning, 84.5 (21.0) and 84.0 (21.3).
                A supplementary patient-held record for radiotherapy outpatients appears to have no effect on satisfaction with communication, participation in care, or quality of life.
These findings reflect the quality of published data regarding interventions for this aspect of the management of radiation induced complications. Although there is grade IC evidence, these studies are not recent, the allocation concealment is unclear in the text, and overall there is a variable level of assessment of the response, emphasising the need for more studies to be conducted with improved designs to clarify the investigative process and support the final result.
