RESUMEN

INTRODUCTION: Small cell prostate cancer (SCPC) is a rare histologic subtype of prostate cancer, for which the optimal staging strategy remains unclear. METHOD: The Surveillance, Epidemiology, and End Results database was used to analyze the incidence and outcomes of SCPC between the years 2004 through 2016. Limited-stage SCPC (LS-SCPC) was defined as SCPC without any metastasis regardless of local invasion. Extensive stage SCPC (ES-SCPC) was defined as any metastasis to lymph nodes and/or to distant organs. RESULT: A total of 403 SCPC patients were included in the study cohort, accounting for 0.056% of all prostate cancer cases (n=719,655). Of the 358 patients with known metastasis status, 275 (76.8%) patients had ES-SCPC, whereas 83 (23.2%) patients had LS-SCPC. LS-SCPC was associated with better overall survival (17 vs. 9 mo, P<0.001) and disease-specific survival (25 vs. 10 mo, P<0.001) compared with ES-SCPC. All LS-SCPC patients had a similar overall survival regardless of T stage. Similarly, all ES-SCPC patients had similar outcomes regardless of metastasis sites. High prostate-specific antigen (PSA) is paradoxically associated with superior outcome in both localized stage patients (PSA≥4 vs. PSA<4, 19 vs. 10 mo, P=0.002) and extensive stage patients (PSA≥20 vs. PSA<20, 13 vs. 9 mo, P=0.02). Multivariate analysis of treatment showed that chemotherapy was associated with improved survival in ES-SCPC with hazard ratio of 0.52. CONCLUSION: Similar to small cell lung cancer, SCPC can be staged into LS-SCPC or ES-SCPC. The binary staging system correlates well with prognosis.

RESUMEN

Urothelial carcinoma with villoglandular differentiation (UCVGD) is a rare aggressive variant of urothelial carcinoma. It is usually associated with high-grade urothelial carcinoma or rarely adenocarcinoma. There is only one other previous report of UCVGD associated with small cell neuroendocrine carcinoma of urinary bladder. We report the second case of UCVGD with small cell neuroendocrine carcinoma of urinary bladder in a 74-year-old non-smoker male patient. The mass was muscle invasive and also invaded the prostate. This entity needs to be confidently diagnosed due to its prognostic and therapeutic implications.

RESUMEN

To investigate the clinical efficacy of autologous cytokine induced killer (CIK) cells transfusion combined with radiochemotherapy in the treatment of advanced cervical cancer. A total of 89 hospitalized patients with advanced cervical cancer were admitted and divided into the treatment group (44 cases, autologous CIK cells transfusion combined with radiochemotherapy) and the control group (45 cases, radiochemotherapy) by a randomized non-blind method. Comparisons of therapeutic efficacies, immune functions, life qualities and survival rates were analyzed between the two groups. The short-term therapeutic efficacy of the treatment group was significantly higher than that of the control group. There was no significant difference in 1, 2 and 3 year survival rates between the two groups. Compared with pre-treatment, levels of CD3+, CD4+/CD8+ in peripheral blood were increased in the CIK group, which were reduced in the control group. In the CIK group,only the feeling was depressed on the 25th day post-treatment (T25) compared with the day before treatment (B1). However in the control group, the function of body, role, social and holistic health was obvious disordered on day T25 compared with day B1. On day T25, there were significant differences in function of body, social and holistic health between two groups. Autologous CIK cells transfusion combined with radiochemotherapy shows better short-term efficacy than radiochemotherapy alone in the treatment of advanced cervical cancer, which obviously improves immune function and life quality of patients with low side effects.

RESUMEN

INTRODUCTION: For limited-stage small-cell lung cancer (LS-SCLC), National Comprehensive Cancer Network guidelines recommend that thoracic radiotherapy (TRT) be delivered concurrently with chemotherapy and early in the regimen, with cycle 1 or 2. Evidence is conflicting regarding the benefit of early timing of TRT. A Korean randomized trial did not see a survival difference between early (cycle 1) and late (cycle 3) TRT. Current United States (US) practice patterns are unknown. MATERIALS AND METHODS: We surveyed US radiation oncologists using an institutional review board-approved online questionnaire. Questions covered treatment recommendations, self-rated knowledge of trials, and demographics. RESULTS: We received 309 responses from radiation oncologists. Ninety-eight percent recommend concurrent chemoradiotherapy over sequential. Seventy-one percent recommend starting TRT in cycle 1 of chemotherapy, and 25% recommend starting in cycle 2. In actual practice, TRT is started most commonly in cycle 2 (48%) and cycle 1 (44%). One-half of respondents (54%) believe starting in cycle 1 improves survival compared with starting in cycle 3. Knowledge of the Korean trial was associated with flexibility in delaying TRT to cycle 2 or 3 (P = .02). Over one-third (38%) treat based on pre-chemotherapy volume. CONCLUSION: US radiation oncologists strongly align with National Comprehensive Cancer Network guidelines, which recommend early concurrent chemoradiotherapy. Nearly three-quarters of respondents prefer starting TRT with cycle 1 of chemotherapy. However, knowledge of a trial supporting a later start was associated with flexibility in delaying TRT. Treating based on pre-chemotherapy volume-endorsed by over one-third of respondents-may add unnecessary toxicity. This survey can inform development of future trials.

RESUMEN

An 80-year-old man with prostate cancer receiving hormone therapy presented with urinary retention. The computed tomographic scan showed metastases to the lung, liver, and lymph nodes, as well as increased prostate volume. Transurethral resection of the prostate (TURP) was performed, and the resected specimen was pathologically found to be a small cell carcinoma of the prostate. The patient was treated with a combination of carboplatin and irinotecan, and achieved a partial response : size reduction of the prostate and the metastatic lesions, and decreased neuron specific enolase (NSE) level. The chemotherapy with carboplatin and irinotecan is reported to have fewer serious adverse effects, and equivalent efficacy to the cisplatin/etoposide chemotherapy. Therefore, this regimen could also be a treatment option for the patients with small cell carcinoma of the prostate.

RESUMEN

Radiotherapy is the standard treatment for cervical cancer, but causes radiotherapy-induced complications. Recently, chemotherapy has been more extensively utilized. Here, we perform a large-scale comparison of chemotherapy and radiotherapy. From 2002 to 2008, 2,268 patients were grouped according to adjuvant radiotherapy or chemotherapy before and/or after surgery, and we compared the 5-year overall survival (OS) and disease-free survival (DFS) rates, recurrence rates, side effects, quality of life (QoL), and sexual activity. There were no significant differences between the treatment groups for the 5-year OS and DFS rates (OS: p = 0.053, DFS: p = 0.095), although marginally improved outcomes were observed in the chemotherapy group (OS: 86.5% vs. 82.8%; DFS: 84.5% vs. 81.4%). However, patients with early-stage disease, clinical response, and younger age had increased 5-year OS and DFS rates following chemotherapy compared to radiotherapy (p<0.05). The chemotherapy group exhibited significantly lower 5-year recurrence and distant failure rates compared to the radiotherapy group (p<0.001 and p = 0.007, respectively). Nausea and vomiting were the most frequent short-term complications of chemotherapy, whereas bowel and urinary complications were more frequent in the radiotherapy group. Compared to the chemotherapy group, patients who received radiotherapy reported a lower QoL, less frequent sexual activity, and more severe menopausal symptoms (p<0.05). Cervical cancer patients treated with chemotherapy, especially those with early-stage disease, clinical responses, and younger ages, have more positive outcomes, fewer complications, better QoL and sexual activity, suggesting that chemotherapy may be a valuable alternative option for selected patients.

RESUMEN

BACKGROUND: To evaluate outcomes using a Thai herbal medicine, Vilac Plus (G716/45) with standard radiotherapy in comparison with historic controls from literature reports of the results of treatment in stage IIIB cervical cancer. MATERIALS AND METHODS: Between March 2003 and June 2005, thirty patients with advanced cervical cancer stage IIIB-IV who had a poor performance status were treated by palliative radiotherapy along with an adjuvant daily dose of 15-30 ml of Thai herbal tonic solution (Vilac Plus G716/45) administered orally three times after meals as an additional supportive therapy. The results were analyzed from the aspect of the overall survival rates with curves estimated by the Kaplan-Meier method. RESULTS: The median follow -up time for stage IIIB was 4.2 years with a range of 7.9 months - 6.1 years. The overall 1, 3, and 5 year survival rates for stage IIIB were 88%, 60% and 52%. CONCLUSIONS: The overall 5 year survival rate for stage IIIB with a poor performance status was 52% when compared with 34-54.8% for historic controls. The combined complementary palliative radiotherapy (CCPR) had low rates of radiation morbidity. It was a simple technique and feasible for developing countries. The pilot study was limited by the small number of patients and further research will be necessary to assess interrelated and confounding factors in treatment of cervical cancer patients.

RESUMEN

OBJECTIVE: To observe the effect of TCM therapy for removing toxic substance and unblocking meridians on post-radiation quality of life (QOF) in 55 patients with lung cancer. METHODS: All patients were randomly assigned to two groups, the 55 patients in the treated group were treated with radiotherapy combined with the TCM therapy, and the 53 in the control group were given radiotherapy alone. The clinical efficacy was evaluated by indexes including KPS scores, QLQ-C30 questionnaire, LC13 specific scale for lung cancer, evaluation criteria for TCM efficacy, the 6-min walking distance, and body weight, etc. RESULTS: The KPS score in the treated group after treatment was improved in 13 patients (23.6%), stabilized in 27 (49.6%) and declined in 15 (27.3%), while in the control group, it was improved in 7 (13.2%), stabilized in 21 (39.6%) and declined in 25 (47.2%), the difference between the two groups was significant (P < 0.05). The results from evaluation with QLQ-C30 questionnaire and LC30 scale in the treated group was also superior to those in the control group (P < 0.05), respectively. The scores of TCM efficacy (24.52 +/- 8.98 vs 29.76 +/- 7.09, P < 0.05) and the 6-min walking distance (233.4 +/- 29.2 m vs 205.8 +/- 31.9 m, P < 0.05) were better in the treated group. After treatment in the treated group, the body weight was increased in 11 patients (20.0%), stabilized in 28 (50.9%) and decreased in 16 (29.1%), while in the control group it was increased in 5 (9.4%), stabilized in 26 (49.1%) and decreased in 22 (41.5%), difference between the two groups was significant, too (P < 0.05). CONCLUSION: TCM therapy for removing toxic substance and unblocking meridians can improve the post-radiation QOL of patients with lung cancer to some extent.

RESUMEN

Lung cancer is the leading cause of cancer-related mortality. Since tobacco smoking is the cause in vast majority of cases, the incidence of lung cancer is expected to rise in those countries with high or rising incidence of tobacco smoking. Even though populations at risk of developing lung cancer are easily identified, mass screening for lung cancer is not supported by currently available evidence. In the case of non-small cell lung cancer, a cure may be possible with surgical resection followed by post-operative chemotherapy in those diagnosed at an early stage. A small minority of patients who present with locally advanced disease may also benefit from pre-operative chemotherapy and/or radiation therapy to down stage the tumor to render it potentially operable. In a vast majority of patients, however, lung cancer presents at an advanced stage and a cure is not possible with currently available therapeutic strategies. Similarly, small cell lung cancer confined to one hemi-thorax may be curable with a combination of chemotherapy and thoracic irradiation followed by prophylactic cranial irradiation, if complete remission is achieved at the primary site. Small cell lung cancer that is spread beyond the confines of one hemi-thorax is, however, considered incurable. In this era of molecular targeted therapies, new agents are constantly undergoing pre-clinical and clinical testing with the aim of targeting the molecular pathways thought be involved in etiology and pathogenesis of lung cancer.

RESUMEN

Cognitive dysfunction is a common occurrence among patients with small-cell lung cancer, with prevalence rates ranging anywhere from 15% to 90%. Although prophylactic cranial irradiation has been described as one culprit to explain these cognitive deficits, other causes also have been implicated. This review provides a summary of the factors that may contribute to cognitive decline in this group of patients and comments upon how cognitive dysfunction or the risk for it might influence patient management.

RESUMEN

PURPOSE/OBJECTIVES: To examine the effects of spirituality on the sense of well-being of people with lung cancer. DESIGN: Descriptive, correlational study. SETTING: Urban and rural oncology and radiation centers. SAMPLE: 60 adults ranging from 33-83 years of age. Most participants had non-small cell lung cancer and were female, Caucasian, and older than 50. METHODS: Participants completed a questionnaire composed of six survey instruments: Life Attitude Profile-Revised, Adapted Prayer Scale, Index of Well-Being, Symptom Distress Scale, a background information sheet, and a cancer characteristics questionnaire. Correlations among study concepts were examined, and multiple regression analysis was used to determine the effects of spirituality. MAIN RESEARCH VARIABLES: Meaning in life, prayer activities and experiences, symptom distress, and psychological well-being. FINDINGS: Higher meaning in life scores were associated with higher psychological well-being and lower symptom distress scores. Higher prayer scores were associated with higher psychological well-being scores. Regression analysis indicated that meaning in life mediated the relationship between functional status and physical responses to lung cancer and explained 9% of the variance in symptom distress. Prayer mediated the relationship between current physical health and psychological responses and explained 10% of the variance in psychological well-being. CONCLUSIONS: Aspects of spirituality, meaning in life, and prayer have positive effects on psychological and physical responses in this group of people with lung cancer. IMPLICATIONS FOR NURSING: This research provides knowledge about spirituality and sense of well-being to guide the care of people with lung cancer.

RESUMEN

Small-cell lung cancer (SCLC) is expected to account for 25% of the approximate 170,000 cases of lung cancer diagnosed in the United States in 2002. Although sensitive and responsive to chemotherapy, SCLC has an increased propensity for early metastases, with relapses being common and long-term survival rates being poor. Clinical trials have played a vital role in expanding our knowledge base for this disease and have resulted in newer modalities, including chemotherapeutic agents, prophylactic cranial irradiation, and thoracic radiotherapy designed to improve overall outcomes. Clinical trials have also served to clarify the role of surgery in a disease that traditionally has been thought to be nonoperable. This review will focus on the results of clinical trials that have had an effect on the treatments of patients with limited and extensive-stage SCLC, with recommendations from the National Comprehensive Cancer Network being emphasized.

RESUMEN

Recent meta-analysis of patients with small cell lung cancer has confirmed the effectiveness of prophylactic cranial irradiation in reducing the cumulative incidence of brain metastases and contributing to a significant increase in 3-year survival. Likewise, with increased median survivals being documented in patients with stage IIIA/B non-small cell lung cancer, there is evidence that the brain is emerging as a significant metastatic target site. Although prophylactic cranial irradiation is a reasonable option to explore, the potential for long-term neuropsychologic adverse effects is of concern in both diagnostic groups. Radiation-induced reactive oxygen intermediates and reactive nitrogen intermediates appear to play a major role in mediating this toxicity. Hypoxic stress results in a significant increase in erythropoietin (EPO) mRNA in mouse brain and, in two models, the administration of EPO improves performance function and prevents cognitive impairment. With the demonstration of EPO receptors in astrocytes, neurons, and brain capillary endothelial cells as well as the ability of EPO to cross the blood-brain barrier, a potential for EPO-mediated central nervous system radioprotection is postulated. The rationale and preliminary design for a phase III study of EPO as a neurocognitive protectant in patients with lung cancer receiving prophylactic cranial irradiation is presented.

RESUMEN

OBJECTIVE: To evaluate the efficacy of combined modality treatment and determine the prognostic factors for small cell lung cancer (SCLC). METHODS: From January 1974 to December 1995, 1260 patients with SCLC treated were retrospectively evaluated, with limited lesions in 732 patients, extensive lesions in 500 and stage unrecorded in 28. 553 patients were alloted into chemotherapy + radiotherapy (C + R) group, 355 into C + R + C group, 97 into R + C group, 126 into C group, 64 into R group and 65 into surgery (S + C + R) group. Patients with limited lesions received 2 - 4 cycles of chemotherapy including COMC, COMP, COMVP and CE-CAP. Radiotherapy was given to a dose of 40 - 70 Gy/4 - 7 w. Radiation portals for patients with limited lesions encompassed the primary tumor, hilar lymphatic drainage areas, partial mediastinum and bilateral supraclavicular regions. Patients with extensive lesions mainly received chemotherapy with or without palliative irradiation. RESULTS: The overall CR and PR rates were 26.7% and 52.3%. Local recurrence and distant metastasis rates were 58.8% and 61.5%. The 1-, 3- and 5-year survival rates were 50.2%, 14.7% and 11.7%, with median survival time of 12 months. The era, sex, age, tumor stage and treatment modality were all significant prognostic factors by both uni-variate and multi-variate analyses (P < 0.05). The result of S + C + R rated the best among these modalities and the result of C + R + C was superior to C + R, though the difference of which was not significant. CONCLUSION: Surgical resection should be considered as one part of comprehensive therapy for small cell lung cancer patients with limited lesions whenever possible. On top of routine chemotherapy early administration of radiotherapy is advisable.

RESUMEN

Lung cancer has long been considered a disease that might benefit from the dose escalation of radio/chemotherapy afforded by a stem cell transplant. However, the clinical experience with high-dose chemotherapy and autologous bone marrow transplantation in lung cancer has been disappointing, with most trials showing little or no improvement in long-term survival. Unfortunately, lung cancer has a tendency to metastasize to the bone marrow, and lung cancer cells are known to circulate in the peripheral blood. Therefore, there is concern that autologous stem cell grafts from lung cancer patients may reinoculate recipients with live tumor cells. Photochemical purging of stem cell grafts with Merocyanine 540 (MC540) is highly effective against a wide range of leukemia and lymphoma cells and is well tolerated by normal hematopoietic stem and progenitor cells. Most solid tumor cells (including lung cancer cells), however, are only moderately sensitive or refractory to MC540-mediated photodynamic therapy (PDT). We report here that postirradiation hyperthermia (< or = 42 degrees C, 3 h) potentiates the MC540-mediated photoinactivation of both wild-type (H69) and cisplatin-resistant mutant (H69/CDDP) small cell lung cancer cells by several orders of magnitude, while only minimally enhancing the depletion of normal human granulocyte/macrophage progenitor cells. Our data suggest that postirradiation hyperthermia provides a simple and effective means of extending the utility of MC540-PDT to the purging of stem cell grafts contaminated with lung cancer and possibly other solid tumor cells.

RESUMEN

OBJECTIVE: To observe the complementary function of moxibustion and Guben Yiliu III (GBYL), a Chinese herbal composite preparation, in combination with chemotherapy. METHODS: Eighty-one patients of middle-late stage malignant tumor were randomly divided into three groups, 16 in the control group treated with chemotherapy alone, 35 in the TCM group treated with chemotherapy combined GBYL and 30 in the TCM combined moxibustion group. The therapeutic effect of treatment was evaluated according to the immediate effect, living quality scoring, etc. RESULTS: The comprehensive living quality score and Karnofsky score dropped significantly in the control group after treatment with significant increase of pain score and decrease of tongue figure score (P < 0.05 or P < 0.01). In the TCM group, the former two criteria lowered less than those in the control group, but no significant difference in the latter two criteria was shown. For those in the TCM combined moxibustion group, all the four criteria were improved better than those in the control group (P < 0.01 or P < 0.05). CONCLUSION: GBYL combined or not combined with moxibustion could improve the living quality of patients received chemotherapy.
