Prophylactic Cranial Irradiation

Masakuni Sakaguchi, Toshiya Maebayashi, Takuya Aizawa, Naoya Ishibashi, Tsutomu Saito
BACKGROUND: Prophylactic cranial irradiation (PCI) is indicated for limited disease (LD) in small cell lung cancer (SCLC) patients who achieve a complete or near-complete response; however, it is sometimes not administered because of possible adverse reactions or patient refusal. Here we assessed treatment outcomes among patients with SCLC who were not treated with PCI. METHODS: The medical records of 60 patients (45 men, 15 women; mean age, 68 years; age range, 51-82 years) with SCLC were retrospectively reviewed...

Small cell lung cancer (SCLC) is a high-grade neuroendocrine tumor characterized by rapid growth, early metastatic spread, and initial responsiveness to therapy. Although the incidence of SCLC is declining, it remains one of the common causes of cancer-related mortality. Initial evaluation of patients with SCLC should focus on determining the extent of disease and the ability of the patient to tolerate specific therapy. Positron emission tomography (PET) can improve the accuracy of staging and treatment planning in many patients...

INTRODUCTION: Data on prophylactic cranial irradiation (PCI) after complete resection of SCLC are limited. The purpose of this study was to investigate the impact of PCI in this population. METHODS: We retrospectively identified completely resected SCLC at the Shanghai Chest Hospital between January 2006 and January 2014. RESULTS: A total of 349 patients (115 patients who received PCI [the PCI-treated cohort] and 234 patients who did not [the non-PCI-treated cohort]) were included in the study...

INTRODUCTION: In patients with non-small cell lung cancer (NSCLC) treated with chemoradiotherapy (CRT), prophylactic cranial irradiation (PCI) is not standard practice. This study determined patient preferences for PCI with respect to survival benefit, reduction in brain metastases (BM) and acceptable toxicity. METHODS: A Discrete Choice Experiment was completed pre- and post-treatment. Patients made 15 hypothetical choices between two alternative PCI treatments described by four attributes: amount of life gained, chance of BM, ability to care for oneself, and loss of memory...

BACKGROUND: Concurrent chemoradiotherapy (CCRT) is the standard treatment for limited-stage small-cell lung cancer (LD-SCLC). However, the efficacy of consolidation chemotherapy (CCT) in LD-SCLC remains controversial despite several studies that were performed in the early years of CCT use. The aim of this study was to reevaluate the effectiveness and toxicities associated with CCT. METHODS: This retrospective analysis evaluated 177 patients with stage IIIA and IIIB small-cell lung cancer (SCLC) who underwent CCRT from January 2001 to December 2013 at Sun Yat-Sen University Cancer Center (SYSUCC)...

Controversial value of prophylactic cranial irradiation (PCI) in NSCLC in terms of survival benefit prompted us to explore the possible risk factors for brain metastasis (BM) during the course of EGFR-TKIs therapy from EGFR-mutated advanced lung adenocarcinoma and identify the potential population most likely to benefit from PCI, because BM remains a therapeutically challenging issue. We retrospectively reviewed the records of 134 patients with EGFR-mutated advanced lung adenocarcinoma between 2008 and 2012...

Radiotherapy for small cell lung carcinoma has known significant improvements over the past 10 years especially through routine use of PET-CT in the initial work-up and contouring before treatment. Prophylactic cranial irradiation remains a standard of care for locally advanced disease and is a subject of controversy for metastatic disease. A new indication for thoracic radiotherapy may soon arise for metastatic disease, still confirmation studies are ongoing.

OBJECTIVE: To evaluate the effect of prophylactic cranial irradiation (PCI) on overall survival (OS) in patients with extensive small cell lung cancer (ESCLC). METHODS: Between April 2005 and May 2014, 204 patients with ESCLC who had any response (according to RECIST 1.1) to initial chemotherapy were reviewed. All patients had undergone appropriate imaging tests to exclude brain metastases before initial chemotherapy. PCI was performed on 45 patients (22.1 %) and the remaining patients (77...

BACKGROUND: Brain metastasis of lung cancer adversely affects overall survival (OS) and quality of life, while peritumoral brain edema is responsible for life-threatening complications. METHODS: We retrospectively analyzed the clinicopathological and cerebral radiological data of 575 consecutive lung cancer patients with brain metastases. RESULTS: In adenocarcinoma and squamous cell carcinoma, peritumoral brain edema was more pronounced than in small-cell lung cancer (p < 0...

BACKGROUND: Many patients with limited disease small cell lung cancer (LD SCLC) suffer from comorbidity. Not all patients with comorbidity are offered standard treatment, though there is little evidence for such a policy. The aim of this study was to investigate whether patients with comorbidity had inferior outcomes in a LD SCLC cohort. MATERIAL AND METHODS: We analyzed patients from a randomized study comparing two three-week schedules of thoracic radiotherapy (TRT) plus standard chemotherapy in LD SCLC...

Small cell lung cancer (SCLC) is an aggressive cancer of neuroendocrine origin, which is strongly associated with cigarette smoking. Patients typically present with a short duration of symptoms and frequently (60-65 %) with metastatic disease. SCLC is a heterogeneous disease including extremely chemosensitive and chemoresistant clones. For this reason, a high percentage of patients respond to first-line chemotherapy but rapidly succumb to the disease. SCLC is generally divided into two stages, limited and extensive...

Radiotherapy has been shown to play a key role in the management of small cell lung cancer. There are well-established data in the literature for the use of concurrent chemoradiotherapy for stage I-III disease, although key questions remain over the timing of radiation, the optimal dose/fractionation and particularly once versus twice daily treatment, the use of elective nodal irradiation and drug combinations. Data for the use of thoracic radiation in stage IV disease, after chemotherapy, have recently become available and are leading to a change in practice...

PURPOSE: Prophylactic cranial irradiation (PCI) involves giving radiation to the entire brain with the goals of reducing the incidence of brain metastasis and improving overall survival. Experimentally, we have demonstrated that PCI prevents brain metastases in a breast cancer mouse model. We developed a computational model to expand on and aid in the interpretation of our experimental results. METHODS AND MATERIALS: MATLAB was used to develop a computational model of brain metastasis and PCI in mice...

Poorly differentiated neuroendocrine tumors are rare but their incidence is rising. High-grade neuroendocrine lung tumors, including small-cell lung cancer, are part of this group. Outside of the lung, they most often arise within the gastrointestinal tract (oesophagus, guts and pancreas) and are called neuroendocrine carcinomas. Due to their rarity, very little is known about neuroendocrine carcinomas of the pancreas and the gastrointestinal tract and few studies have been done. Therefore, most therapeutic recommendations are issued from studies on small-cell lung cancers...

AIM: Elderly patients require special consideration in oncology treatment. Small-cell lung cancer (SCLC) is a highly aggressive tumour with dismal prognosis. The present study focused on prognostic factors in elderly patients irradiated for limited-disease SCLC. PATIENTS AND METHODS: In 36 patients aged ≥65 years, 11 factors were evaluated for the impact on survival, namely gender, Karnofsky performance score, body mass index, T-category, N-category, tobacco consumption, time from SCLC diagnosis to irradiation, smoking during irradiation, simultaneous chemotherapy, radiation dose and prophylactic cranial irradiation...

BACKGROUND: Prophylactic cranial irradiation (PCI) was reported to offer survival benefits in patients with limited stage small-cell lung cancer (LS-SCLC). However, earlier studies did not routinely use positron emission tomography (PET) as part of the initial evaluation, thereby reducing the accuracy of tumor staging. We examined the effect of more accurate staging with PET on the role of PCI in patients with LS-SCLC. PATIENTS AND METHODS: We retrospectively collected data from 280 patients with LS-SCLC who had objective responses after combined chemoradiotherapy between 2001 and 2013...

Stereotactic body radiation therapy (SBRT) can significantly improve the treatment outcomes of patients with inoperable stage I non-small-cell lung cancer. Similarly, a few case studies have reported the effectiveness of SBRT for stage I small-cell lung cancer (SCLC). However, no study has investigated the use of SBRT for extensive-stage SCLC (ES-SCLC). Compared with conventional RT, SBRT is able to deliver a higher radiation dose precisely and safely to small targets in short-duration treatments. The present study reports the outcome of a patient with ES-SCLC who responded favorably to initial chemotherapy and received SBRT for a residual mass in the peripheral lung...
