Current guidelines for the management of small cell lung cancer

An algorithmic approach utilizing CK7, TTF1, beta-catenin, CDX2, and SSTR2A can help differentiate between gastrointestinal and pulmonary neuroendocrine carcinomas

Primary gastrointestinal neuroendocrine carcinoma (GI-NEC) cannot be distinguished morphologically from pulmonary neuroendocrine carcinoma (P-NEC). This can present a significant diagnostic challenge in cases where site of origin cannot be readily determined. To identify immunohistochemical (IHC) markers that can be used to reliably distinguish between GI-NECs and P-NECs, we constructed 3-mm tissue microarrays, one containing 13 GI-NECs and one containing 20 P-NECs. IHC was performed on both microarrays using 21 stains: AE1/AE3, CK7, CK20, synaptophysin, chromogranin, CD56, INSM1, SSTR2A, CDX2, SATB2, TTF1, Napsin A, PR, GATA3, PAX8, ISL1, beta-catenin, AFP, SMAD4, Rb, and p53. For GI-NEC, the most strongly expressed marker was synaptophysin (mean H-score 248), while AE1/AE3 was the most strongly expressed in P-NEC (mean H-score 230), which was stronger than in GI-NEC (p = 0.011). Other markers that were stronger overall in P-NEC than in GI-NEC included CK7 (p < 0.0001) and TTF1 (p < 0.0001). Markers that were stronger overall in GI-NEC than in P-NEC included SSTR2A (p = 0.0021), SATB2 (p = 0.018), CDX2 (p = 0.019), and beta-catenin (nuclear; p = 0.029). SMAD4, Rb, and p53 showed similar rates of abnormal protein expression. Based on these results, a stepwise algorithmic approach utilizing CK7, TTF1, beta-catenin, CDX2, and SSTR2A had a 91% overall accuracy in distinguishing these GI-NEC from P-NEC. This was tested on a second cohort of 10 metastatic GI-NEC and 10 metastatic P-NEC, with an accuracy in this cohort of 85% and an overall accuracy of 89% for the 53 cases tested. Our algorithm reasonably discriminates GI-NEC from P-NEC using currently available IHC stains.

ACR Appropriateness Criteria® Noninvasive Clinical Staging of Primary Lung Cancer

Lung cancer is the leading cause of cancer-related deaths in both men and women. The major risk factor for lung cancer is personal tobacco smoking, particularly for small-cell lung cancer (SCLC) and squamous cell lung cancers, but other significant risk factors include exposure to secondhand smoke, environmental radon, occupational exposures, and air pollution. Education and socioeconomic status affect both incidence and outcomes. Non-small-cell lung cancer (NSCLC), including adenocarcinoma, squamous cell carcinoma, and large cell carcinoma, comprises about 85% of lung cancers. SCLC accounts for approximately 13% to 15% of cases. Prognosis is directly related to stage at presentation. NSCLC is staged using the eighth edition of the tumor-node-metastasis (TNM) criteria of the American Joint Committee on Cancer. For SCLC the eighth edition of TNM staging is recommended to be used in conjunction with the modified Veterans Administration Lung Study Group classification system distinguishing limited stage from extensive stage SCLC. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Early treatment volume reduction rate as a prognostic factor in patients treated with chemoradiotherapy for limited stage small cell lung cancer

Purpose

To investigate the relationship between early treatment response to definitive chemoradiotherapy (CRT) and survival outcome in patients with limited stage small cell lung cancer (LS-SCLC).

Materials and Methods

We retrospectively reviewed 47 patients with LS-SCLC who received definitive CRT between January 2009 and December 2012. Patients were treated with systemic chemotherapy regimen of etoposide/carboplatin (n = 15) or etoposide/cisplatin (n = 32) and concurrent thoracic radiotherapy at a median dose of 54 Gy (range, 46 to 64 Gy). Early treatment volume reduction rate (ETVRR) was defined as the percentage change in gross tumor volume between diagnostic computed tomography (CT) and simulation CT for adaptive RT planning and was used as a parameter for early treatment response. The median dose at adaptive RT planning was 36 Gy (range, 30 to 43 Gy), and adaptive CT was performed in 30 patients (63.8%).

Results

With a median follow-up of 27.7 months (range, 5.9 to 75.8 months), the 2-year locoregional progression-free survival (LRPFS) and overall survival (OS) rates were 74.2% and 56.5%, respectively. The mean diagnostic and adaptive gross tumor volumes were 117.9 mL (range, 5.9 to 447 mL) and 36.8 mL (range, 0.3 to 230.6 mL), respectively. The median ETVRR was 71.4% (range, 30 to 97.6%) and the ETVRR >45% group showed significantly better OS (p < 0.0001) and LRPFS (p = 0.009) than the other group.

Conclusion

ETVRR as a parameter for early treatment response may be a useful prognostic factor to predict treatment outcome in LS-SCLC patients treated with CRT.

Prostate cancer and neuroendocrine differentiation: more neuronal, less endocrine?

Neuroendocrine differentiation (NED) marks a structural and functional feature of certain cancers, including prostate cancer (PCa), whereby the malignant tissue contains a significant proportion of cells displaying neuronal, endocrine, or mixed features. NED cells produce, and can secrete, a cocktail of mediators commonly encountered in the nervous system, which may stimulate and coordinate cancer growth. In PCa, NED appears during advanced stages, subsequent to treatment, and accompanies treatment resistance and poor prognosis. However, the term “neuroendocrine” in this context is intrinsically vague. This article seeks to provide a framework on which a unified view of NED might emerge. First, we review the mutually beneficial interplay between PCa and neural structures, mainly supported by cell biology experiments and neurological conditions. Next, we address the correlations between PCa and neural functions, as described in the literature. Based upon the integration of clinical and basic observations, we suggest that it is legitimate to seek for true neural differentiation, or neuromimicry, in cancer progression, most notably in PCa cells exhibiting what is commonly described as NED.

A microRNA-related single nucleotide polymorphism of the XPO5 gene is associated with survival of small cell lung cancer patients

MicroRNA (miRNA)-related single nucleotide polymorphisms (miR-SNPs) in miRNA processing machinery genes affect cancer risk, treatment efficacy and patient prognosis. A miR-SNP of rs11077 located in the 3'UTR of miRNA processing machinery gene XPO5 was examined in small cell lung cancer (SCLC) patients to evaluate its association with cancer survival. A total of 42 patients were enrolled in the present study and genotyped for rs11077 and survival was assessed using the Kaplan-Meier method, as well as univariate and multivariate analyses. The AA genotype of rs11077 was identified for its significant association with better survival time (P=0.023). In addition, rs11077 was found to associate independently with overall survival in SCLC patients by multivariate analysis (relative risk 2.469; 95% CI, 1.088-5.603; P=0.031). The findings of this study suggest that although miR-SNP studies for miRNA processing machinery genes are still at an early age, miR-SNPs have an impact on cancer survival. In conclusion, a miR-SNP in the 3'UTR region of the XPO5 gene was identified as an independent prognostic marker for survival of advanced SCLC patients.

A polymorphism at the miR-502 binding site in the 3' untranslated region of the SET8 gene is associated with the outcome of small-cell lung cancer

microRNAs (miRNAs) bind to the 3' untranslated regions (UTRs) of messenger RNAs, where they interfere with translation of genes that regulate cell differentiation, apoptosis and tumourigenesis. The histone methyltransferase SET8 has been reported to methylate TP53 and regulate genomic stability. We analysed a single nucleotide polymorphism (rs16917496) within the miR-502 miRNA seed region at the 3' UTR of SET8 in small-cell lung cancer (SCLC) patients. The SET8 CC+CT genotype was identified to be independently associated with longer survival in SCLC patients by multivariate analysis (relative risk, 0.453; 95% CI 0.217-0.944; p=0.035). The analysis of genetic polymorphisms in miRNA binding sites may help to identify patient subgroups at high risk of poor outcome.

Chronic cough: a multidisciplinary approach

BACKGROUND AND METHODS

Chronic cough is defined as a cough persisting for more than eight weeks. This condition generates significant healthcare and economic costs. It is associated with a spectrum of disorders across multiple medical specialties and can provide significant challenges for effective evaluation and management. The current literature was reviewed to gain further insight into chronic cough, including its relationship with sinonasal disease.

RESULTS

Within the reviewed literature, there was strong emphasis on post-nasal drip syndrome as a major causative factor.

CONCLUSION

Cough is the most common complaint for which adult patients seek medical consultation in primary care settings. Chronic cough is associated with a deterioration in the quality of patients' lives. Thorough assessment of a patient with a chronic cough relies on a multidisciplinary approach.

Bronchogenic carcinoma after lung transplantation: characteristics and outcomes

BACKGROUND

Lung cancer may occur in the lung transplant population because many patients are former smokers. Not much is known about risk factors and outcomes in these patients.

METHODS

We performed a search of the lung transplant database at our institution to identify patients who had been diagnosed with lung cancer. Records and reports were reviewed for demographics, risk factors for malignancy, lung transplant characteristics, radiographic characteristics, treatment, and outcomes.

RESULTS

We identified 12 lung transplant patients with bronchogenic carcinoma at our institution [age 47.2 +/- 13.2 years (mean +/- SD); 7 (58%) men and 5 (42%) women]. Eleven patients were transplanted for chronic obstructive pulmonary disease (COPD). Time from transplantation to diagnosis of cancer was 119 (21-416) [mean (range)] weeks. Eleven cancers occurred in the native lung; most common cancer cell types were adenocarcinoma (N = 5). Incidence among patients with COPD, who received single lung transplantation was 5.15%. Time from diagnosis of bronchogenic carcinoma to death was 10.8 (1-60) [mean (range)] weeks with a 75% (9/12) 1-year mortality.

CONCLUSIONS

Among our patients, almost all cancers occurred in native lung in ex-smokers who received a lung transplant for COPD. The cancer was often an incidental finding on a routine chest radiograph; however, the disease was usually at an advanced stage at diagnosis, limiting therapeutic options.

Chronic cough: state-of-the-art review

Cough is the most common presenting complaint in adults seeking medical treatment in an ambulatory setting. Chronic cough (persisting greater than 3 weeks) can be associated with myriad diseases that may overlap multiple medical specialties. For this reason, a thorough assessment of the patient with chronic cough relies on a multidisciplinary approach and close cooperation between pulmonary medicine, gastroenterology, and otolaryngology. Despite this daunting task, success can be achieved in up to 90% of patients with chronic cough if a systematic and thorough approach is used. The purpose of this review is to summarize the state-of-the-art in the diagnosis and treatment of chronic cough for the practicing otolaryngologist.

The pulmonary status of patients with limited-stage small cell lung cancer 15 years after treatment with chemotherapy and chest irradiation

STUDY OBJECTIVES

To describe pulmonary symptoms, signs, pulmonary function, and lung imaging studies in patients with limited-stage small cell lung cancer (SCLC) 2 to 15 years after receiving treatment with chemotherapy and chest radiotherapy.

DESIGN

Retrospective review of clinical records and radiographic studies of patients treated in three different prospective combined-modality studies.

SETTING

Federal hospital.

PATIENTS

One hundred fifty-six patients with SCLC who were enrolled between 1974 and 1994.

INTERVENTIONS

Patients with limited-stage SCLC treated on prospective therapeutic studies of combined chemotherapy and radiation therapy were identified. Pulmonary symptoms, physical findings, pulmonary function tests, arterial blood gas measurements, and chest imaging studies were assessed at baseline, and at 1 to 2 years, at 3 to 5 years, and at > 5 years following the initiation of treatment.

MEASUREMENTS AND RESULTS

Initial symptoms included cough in 84 (55%), dyspnea in 59 (39%), and sputum production in 26 (17%). Twenty-three patients lived beyond 5 years (15%) without evidence of recurrence. Seven of these 5-year survivors were without pulmonary symptoms. Pulmonary function test results showed no significant changes in percent predicted values for FVC, FEV(1), and FEV(1)/FVC ratio over the time periods reviewed. The percent predicted values for the diffusing capacity of the lung for carbon monoxide decreased from 71% before the start of treatment to 56% (p < 0.032) at 1 to 2 years. Values improved in most patients beyond 5 years after starting treatment. Radiologist interpretations of chest imaging studies were available for 17 of 23 patients surviving > 5 years. Most patients had minimal to no changes in imaging study findings beyond 5 years.

CONCLUSIONS

Long-term survivors with limited-stage SCLC who were treated with combined chemotherapy and chest radiotherapy have minimal changes in pulmonary symptoms or function from 5 to 15 years after the start of treatment. A concern for late toxicity from combined-modality therapy should not dissuade clinicians from offering therapy with potentially curative result with minimal to no pulmonary dysfunction.

Topotecan in the first-line treatment of small cell lung cancer

Small cell lung cancer (SCLC) is generally sensitive to first-line chemotherapy, but limited disease often recurs and extensive disease is rarely curable. The most common first-line therapy regimen is cisplatin (Platinol; Bristol-Myers Squibb; Princeton, NJ) plus etoposide (Etopophos; Bristol-Myers Squibb)--PE, which is associated with overall response rates >80% in patients with limited SCLC. Although it is associated with median survival times of approximately 18-20 months for limited disease, PE yields median survival times of only approximately 8-12 months in patients with extensive disease, and symptom palliation becomes the primary therapeutic goal. The toxicities of PE may undermine quality of life and leave patients more susceptible to adverse events during subsequent therapies. Topotecan (HYCAMTIN; GlaxoSmithKline; Philadelphia, PA), an established treatment for recurrent SCLC, is being investigated in the first-line setting because of its novel mechanism of action; predictable, noncumulative, and manageable toxicities; and potential synergy with other active agents. Several recent phase II trials have generated promising results for topotecan-based combination regimens, including topotecan/paclitaxel (TAXOL; Bristol-Myers Squibb) (overall response rates 45%-100%), topotecan/etoposide (overall response, 95%), and topotecan, paclitaxel, and platinum agent triplets (overall response rates 51%-93%). The most frequent serious toxicity associated with these regimens was reversible and noncumulative neutropenia, which was generally manageable with supportive care. Additional clinical trials to investigate topotecan-based combination regimens and confirm their role in the first-line treatment of SCLC are under way.

Plasma DNA microsatellite panel as sensitive and tumor-specific marker in lung cancer patients

The majority of lung cancer patients have tumor-derived genetic alterations in circulating plasma DNA that could be exploited as a diagnostic tool. We used fluorescent microsatellite analysis to detect alterations in plasma and tumor DNA in 34 patients who underwent bronchoscopy for lung cancer, including 11 small cell lung cancer (SCLC) and 23 nonsmall cell lung cancer (NSCLC) (12 adenocarcinomas, 11 squamous cell carcinomas) and 20 controls. Allelotyping was performed with a selected panel of 12 microsatellites from 9 chromosomal regions 3p21, 3p24, 5q, 9p, 9q, 13q, 17p, 17q and 20q. Plasma DNA allelic imbalance (AI) was found in 88% (30 of 34 patients), with a similar sensitivity in SCLC and NSCLC. In the 24 paired available tumor tissues, 83% (20 of 24) presented at least 1 AI. Among these patients, 85% (17 of 20) presented also at least 1 AI in paired plasma DNA, but the location of the allelic alterations in paired plasma and tumor DNA could differ, suggesting the presence of heterogeneous tumor clones. None of the 20 controls displayed plasma or bronchial DNA alteration. A reduced panel of six markers (at 3p, 5q, 9p, 9q) showed a sensitivity of 85%. Moreover, a different panel of microsatellites at 3p and 17p13 in SCLC and at 5q, 9p, 9q and 20q in NSCLC patients could be specifically used. Analysis of plasma DNA using this targeted panel could be a valuable noninvasive test and a useful tool to monitor disease progression without assessing the tumor.

Small cell lung cancer survival: 3 years as a minimum for predicting a favorable outcome

OBJECTIVES

To define the minimum survival time indicating a significantly reduced risk of recurrence of small cell lung cancer (SCLC) basing on the evaluation of survival of patients (pts) with SCLC who underwent anatomic staging and were exposed to combination chemotherapy (CT) (including combined modality treatment).

METHODS

Eight pts being our 'historic' group submitted to the NCI Registry for Long Term Survivors with SCLC (est. 1977) and a following 657 unselected pts diagnosed, staged, treated and undergoing life-long follow-up at a single institution between the years 1981 and 1996. For those among our pts who had no evidence of metastatic disease, but had not undergone thorough staging, we have arbitrarily created an intermediate group referred to as 'XD'.

RESULTS

Of the 657 pts 111 survived 2 years or more. Among these 111 there were 88 pts with LD at presentation, 11 with 'XD' and 12 with ED. Of the 111 pts surviving 2 years 51 (51/111) were re-treated for relapse before 24 months. From this group of 111 2 year-or-more survivors 45 (41%) died between 2 and 3 years. From year 3 onwards mortality decreased substantially-eight pts died in the 3-4 year interval and eight in the 4-5 interval-accounting for 14% of all the 2 year survivors. We did not observe any failure of the primary tumor beyond a period of 5 years-both in our 'historic' and the analyzed group. After 5 years development of a second primary tumor, mainly lung cancer, is one of the major causes of death in pts 'cured' of their primary tumor.

CONCLUSION

The shortest survival-time which allows predicting a significantly reduced risk of recurrence of SCLC is 3 years. The same landmark was achieved with the estimation of hazard function and allowed to find a remarkably decreased risk of death at the point of 3 years.

Outcome of patients admitted to the intensive care unit with newly diagnosed small cell lung cancer

Patients with newly diagnosed small cell lung cancer (SCLC) may be considered for admission to an intensive care unit (ICU). Even though SCLC is highly responsive to chemotherapy, it is not clear whether patient outcomes justify the resource use of an ICU. This paper reports the results of a retrospective review of 20 newly diagnosed cases of SCLC who were admitted to one of three ICUs in Melbourne, Australia. Patients who had more than one negative prognostic factor did uniformly poorly, with no survivors beyond 4 months. Five patients were treated with chemotherapy whilst intubated and receiving mechanical ventilatory support. Two of these patients responded to chemotherapy and were extubated 4 days later. Both of these patients were alive and free of tumour recurrence 7 months later. In contrast, patients not treated with chemotherapy died early (within 40 days). We conclude that some patients with SCLC achieve a medium to long-term survival following treatment with chemotherapy instituted during or around the time of their admission to an ICU. The admission to an ICU of selected patients with SCLC may be justified, and prognostic indicators may be of benefit in making these difficult treatment decisions.

Small cell lung carcinoma (SCLC): a clinicopathologic study of 100 cases with surgical specimens

Separation of small cell lung carcinoma (SCLC) from nonsmall cell lung carcinoma (NSCLC) is a critical distinction to be made in the diagnosis of lung cancer. However, the diagnosis of SCLC is most commonly made on small biopsies and cytologic specimens, and practicing pathologists may not be familiar with all its morphologic guises and frequent combination with NSCLC elements, which may be seen in larger specimens. Following the most recent WHO classification of lung tumors and with the hope of identifying prognostic markers, we examined in detail the histology of 100 surgical biopsies or resections with a diagnosis of SCLC from the AFIP and pathology panel of the International Association for the Study of Lung Cancer (IASLC). Multiple clinical and histologic features were studied by Kaplan-Meier analysis. Neuroendocrine architectural patterns, including nested and trabecular growth, with peripheral palisading and rosette formation were common in SCLC. Necrosis and apoptotic debris was prominent in all cases, but crush artifact was infrequent. Cell size in surgical biopsy specimens appears larger than in bronchoscopic biopsy specimens and occasional cells may show prominent nucleoli and vesicular nuclear chromatin, but this does not preclude the diagnosis of SCLC. A high percentage of cases (28%) showed combinations with NSCLC, with large cell carcinoma the most common, followed by adenocarcinoma and squamous cell carcinoma. Because of the frequency of a few scattered large cells in SCLC, we arbitrarily recommend that at least 10% of the tumor show large cell carcinoma before subclassification as combined SC/LC. However, combined SCLC is easily recognized if the additional component consists of other NSCLC subtypes such as adenocarcinoma or squamous cell carcinoma, so no percentage requirement is needed. Stage remained the only predictor of prognosis.

Ten-year follow-up of Southwest Oncology Group 8269: a phase II trial of concomitant cisplatin-etoposide and daily thoracic radiotherapy in limited small-cell lung cancer

PURPOSE

To report the long-term follow-up of Southwest Oncology Group-8269, a phase II North American cooperative group trial of concurrent cisplatin, etoposide, vincristine (PEV), and thoracic radiotherapy (TRT) for limited small-cell lung cancer (L-SCLC).

METHODS

114 eligible patients from 47 institutions enrolled between April, 1985 and March 1986. Patients had documented L-SCLC. Induction chemotherapy consisted of three cycles of PEV. TRT was administered at 1.8 Gy/fraction in 25 daily fractions to a total dose of 45 Gy, to begin concomitantly. Consolidative chemotherapy included two cycles of vincristine, methotrexate, etoposide, doxorubicin and cyclophosphamide. Prophylactic cranial irradiation (PCI) was concurrent with the 3rd cycle of chemotherapy. The PCI dose was 30 Gy in 15 fractions of 2 Gy/fraction.

RESULTS

As of May 2000, 5 of 114 remain alive and progression-free with a minimum follow-up interval of 13.2 years, as of May 2000. The median follow-up interval is 14.2 years. Thirty eight patients died of causes other than SCLC and five patients are still alive and progression-free. Of the remaining 71 patients dying of SCLC, local failure (LF) occurred in 24% (17 patients), distant metastasis (DM) occurred in 35% (25 patients), simultaneous LF and DM occurred in 25% (18 patients), and was indeterminate in 16% (11 patients). Thus, LF was a component of failure in 49%. Twenty patients had the CNS as the initial site of failure. Eleven patients (10%) developed fatal second primary cancers, including two with acute myelogenous leukemia, two with squamous cell lung cancer, one each with breast, pancreas, prostate, renal cell, and myelodysplasia. One patient developed both a melanoma and non-Hodgkin's lymphoma.

CONCLUSION

There are long-term survivors with concomitant TRT and PEV. LF and DM are common. Pattern of failure suggests needs to improve local and systemic control.

Increased risk of secondary cancers in patients with primary cutaneous T cell lymphoma

As putative etiologic factors of primary cutaneous T cell lymphomas may have a general cancerogenic effect, we wanted to assess the risk of secondary malignancies in 319 patients diagnosed with histopathologically verified cutaneous T cell lymphomas and reported to the Finnish Cancer Registry during the years 1953-95. Standardized incidence ratios were defined as the ratio of observed to expected numbers of cases. To obtain the expected numbers of cancer, age-, sex-, and period-specific Finnish incidence rates were applied to the appropriate person-years under observation. Ninety-five percent confidence intervals were calculated assuming a Poisson distribution. For the whole period, we detected 36 secondary cancers whereas 26 were expected (standardized incidence ratios 1.4, 95% confidence intervals 1.0-1.9). The overall risk of lung cancer was significantly increased (standardized incidence ratio was 2.7, 95% confidence intervals were 1.4-4.8); and in particular small-cell lung cancer showed high standardized incidence ratios (standardized incidence ratio was 8.5, 95% confidence intervals were 2.8-20). Also, the risk of lymphomas was elevated (standardized incidence ratios for Hodgkin and non-Hodgkin lymphomas combined were 7.0, 95% confidence intervals were 1.9-18). The incidence of other cancers was similar to the national ratios. An increased risk of secondary cancers and in particular small-cell cancer of the lung and lymphomas among patients with primary cutaneous T cell lymphoma is demonstrated. In clinical practice, lung cancer and lymphomas must be kept in mind when following up patients with cutaneous T cell lymphomas.

Detection of microsatellite alterations in the DNA isolated from tumor cells and from plasma DNA of patients with lung cancer

In this paper, we show that the same panel of three microsatellite markers is useful for the detection of alterations in the DNA of tumor cells and plasma from patients diagnosed with SCLC and NSCLC. In 31% of the SCLC patients, we detected a microsatellite alteration(s) or LOH in at least one locus. In the group of patients diagnosed with NSCLC, a microsatellite alteration or LOH was detected in at least one locus in 33% of the patients. In all but 2 patients, the identical alteration observed in the DNA from tumor cells was also detected in the DNA isolated from blood plasma. This work confirms the results described by other groups and it extends the diagnostic possibilities of finding tumor cell-specific DNA alterations also in the DNA freely circulating in plasma and serum of patients with cancer.
