Small Cell Lung Cancer in Norway: Patterns of Care by Health Region and Survival Trends.

INTRODUCTION/BACKGROUND: There has been a marked survival improvement for patients with non-small-cell lung cancer. We describe the national trends in characteristics and survival, and geographical differences in diagnostic workup, treatment, and survival for patients with small-cell lung cancer (SCLC). MATERIALS AND METHODS: Patients registered with SCLC at the Cancer Registry of Norway in 2002 to 2022 were included. Trends in overall survival were estimated for all SCLC patients, patients with limited stage SCLC, patients undergoing surgery, and by health region. Adjusting for case-mix, a multivariable Cox regression was performed examining the association between health region and death. RESULTS: The study included 8374 patients. The stage distribution remained unchanged during the study period. The 5-year overall survival increased from 7.7% to 22.8% for patients with limited stage. The use of multidisciplinary team meetings varied from 62.5% to 85.7%, and the use of positron emission tomography-computer tomography varied from 70.4% to 86.2% between the health regions. Treatment patterns differed markedly between the health regions, with the proportion dying without any registered treatment ranging from 1.2% to 10.9%. For limited stage patients in 2018 to 2022, the median overall survival ranged from 16.5 to 25.5 months across health regions, and the 5-year overall survival ranged from 18.7% to 28.7% (P = .019). CONCLUSION: The survival for patients with SCLC remains poor. The use of diagnostic procedures, treatment modalities, and survival differed between regions, warranting investigations to further explore the reasons.

Atezolizumab and stereotactic body radiotherapy in patients with advanced non-small cell lung cancer: safety, clinical activity and ctDNA responses-the ComIT-1 trial.

The introduction of immune checkpoint inhibitors has transformed the treatment landscape of metastatic non-small cell lung cancer. However, challenges remain to increase the fraction of patients achieving durable clinical responses to these drugs and to help monitor the treatment effect. In this phase II trial, we investigated the toxicity, systemic responses and circulating tumour DNA responses in patients (n = 21) with advanced non-small-cell lung cancer treated with atezolizumab and stereotactic body radiotherapy in the second or later line. We found the combined treatment to be safe with grade 3 toxicity reported in three patients. As the best overall response, four patients had a partial response, eight had stable disease and five had progressive disease. Median overall survival time was still not reached after a median follow-up of 26.5 months and 10/15 patients with programmed death-ligand 1 negative tumours were alive >18 months after the start of the study treatment. ctDNA was detectable at baseline in 11 patients. A rapid decline in ctDNA to <30% of baseline levels was seen in three patients, two of which were radiographic responders and one was considered clinically benefiting from therapy for almost 1 year.

Randomized phase III trial comparing switch-maintenance pemetrexed with observation followed by pemetrexed at progression in advanced NSCLC.

Objectives: Two phase III trials show that maintenance pemetrexed therapy after platinum-doublet chemotherapy prolongs overall survival (OS) and progression free survival (PFS) in advanced non-squamous non-small-cell lung cancer (NSCLC). However, few patients in the control arms received pemetrexed at progression in these trials, performance status (PS) two patients were ineligible and few of the participants were elderly. Thus, we designed this study comparing immediate switch-maintenance pemetrexed therapy with pemetrexed at progression after platinum-doublet chemotherapy.Methods: Patients with stage IIIB/IV non-squamous NSCLC, ≥18 years, PS 0-2, and non-progression after four courses of carboplatin/vinorelbine were randomized to receive immediate maintenance pemetrexed therapy or observation followed by pemetrexed at progression. The primary endpoint was OS, secondary endpoints were PFS, toxicity and health related quality of life (HRQoL).Results: 105 patients were randomized between May 2014 and September 2017. Median age was 67 years, 36% were >70 years, 9% had PS 2, 91% stage IV and 47% were women. In the observation arm, 73% received pemetrexed at progression. Patients in the maintenance arm had a numerically longer OS (median 12.0 vs. 10.0 months; p = .10) and a statistically significant longer PFS (median 3.1 vs. 1.9 months; p < .01). In multivariable analyses adjusting for baseline characteristics, there was a trend toward improved OS (HR 0.65, 95% CI 0.42-1.01); p = .05), and a significantly improved PFS (HR 0.53, 95% CI 0.35-0.80; p < .01). There were no significant differences in toxicity or HRQoL between the treatment arms.Conclusion: There was a trend toward prolonged OS and significantly longer PFS from switch- maintenance pemetrexed therapy when 73% of patients in the control arm received pemetrexed at progression.

Increase in curative treatment and survival of lung cancer in Norway 2001-2016.

We have studied the alterations in the use of curative treatment and the outcome for lung cancer patients in Norway 2001-2016. The Cancer Registry of Norway has a practically complete registration of all cancer diagnoses, treatments given and deaths. For the years 2001-2016, 43,137 patients were diagnosed with lung cancer. Stereotactic radiotherapy was established nationwide from 2008 and its use has increased, and in 2016, 8.8% were given this treatment. In addition 20.6% were operated and 8.5% were treated with conventional radiotherapy. Thus 37.9% of those diagnosed were treated with intention to cure, compared to 22.9% in 2001 (p < 0.0001). Further, the median survival for the whole group diagnosed with lung cancer increased from 6.0 (95% CI 5.6-6.7) months in 2001 to 11.8 (95% CI 10.9-12.7) in 2016. The 5 year survival increased from 9.4 (95% CI 8.1-10.8)% to 19.9 (95% CI 19.2-20.6)% in the same period. In 2016 the age adjusted incidence rate was 59.5 per 100,000 (Norwegian standard) and had increased significantly in both sexes. There had also been an increase in mean age at diagnosis and the proportion diagnosed in an early stage. The increase in curative treatment has been paralleled with a doubling in both the median and 5-year survival. The present results are used for surveillance and as a benchmark, and we are looking forward to reaching a proportion of 40% of patients given curative treatment.

Substantial nation-wide improvement in lung cancer relative survival in Norway from 2000 to 2016.

INTRODUCTION: There have been significant changes in both diagnostic procedures and therapy for lung cancer since the beginning of the millennium. National incidence and survival data from 2000 through 2016 are studied. METHODS: National data on cancer incidence and vital status are virtually complete. Changes in incidence and survival are described by absolute numbers, percentages, and calculation of relative survival (period analysis). RESULTS: A total of 44,825 individuals were diagnosed with lung cancer in Norway in the study period. The number of incident cases increased with 49% whereas the prevalence increased with 136% from 2000 to 2016. Age-standardised rates rose markedly for women and levelled off for men. In 2016, adenocarcinoma accounted for about 50% of all lung cancers, slightly more for women than for men. The entity "NSCLC not otherwise specified" declined from 24% to 13%, and the fraction of patients with metastatic disease decreased from 54% to 46% during the period, for both sexes combined. The overall median survival time doubled for women and men, reaching 14.3 months and 11.4 months, respectively. For patients with metastatic disease, median survival time showed a small increase but remained less than 6 months. The overall 5-year relative survival increased from 16% to 26% in women and from 16% to 22% in men. The corresponding improvements for the subgroup of non-surgically treated cases with localised disease, were up from 25% to more than 40% in females, and from 10% to almost 40% in males. CONCLUSION: There have been notable changes in incidence patterns and a remarkable improvement in survival for lung cancer over the last 17 years, most markedly for patients without distant metastases at the time of diagnosis. Hopefully, survival will improve even more when immunotherapy is implemented.

Pembrolizumab as second-line therapy in non-small cell lung cancer in northern Norway: budget impact and expected gain-a model-based analysis.

BACKGROUND: Pembrolizumab is a new drug approved in several countries for second-line therapy in non-small cell lung cancer (NSCLC) being programmed cell death ligand (PD-L1) positive. This drug has a high cost, and the cost-effectiveness ratio has been debated. PATIENTS AND METHODS: The budget impact to the Northern Norwegian Regional Health Authority trust of implementing pembrolizumab in second-line therapy in patients with PD-L1-positive NSCLC was calculated. A model was developed employing data from the Cancer Registry of Norway, the KEYNOTE-010 study, the price list from The Hospital Pharmacy of North Norway, the cost of analysing PD-L1 expression and the cost of travelling. Today's cost of second-line therapy was compared with the new standard employing pembrolizumab. The sale price of pembrolizumab in Norway was not published due to price confidentiality. Norwegian krone (NKr) was converted into Euros (€) at a rate of 1€=Nkr 8.8138. (Bank of Norway, 21 February 2017). RESULTS: 105 new patients were identified available for pembrolizumab per year. The annual cost of pembrolizumab was €5.2 million, hospital pharmacy administration costs €0.1 million, PD-L1 testing €0.3 million, oncologist/pulmonologist/nurses €0.2 million, radiology €0.06 million and transportation €0.4 million. Savings due to avoided present second-line therapy was calculated €0.4 million. Consequently, the cost of implementing pembrolizumab was €5.5 million and the annual budget impact was €5.0 million. A mean gain of at least 9 months per patient treated was necessary to make pembrolizumab cost-effective. CONCLUSIONS: The net budget impact of pembrolizumab was €5.0 million. The expenditure could not be indicated cost-effective. Price confidentiality is a growing problem in health economics and it has become a 'menu without prices' setting.

How Do Elderly Poor Prognosis Patients Tolerate Palliative Concurrent Chemoradiotherapy for Locally Advanced Non-Small-Cell Lung Cancer Stage III? A Subset Analysis From a Clinical Phase III Trial.

BACKGROUND: In a phase III trial of patients with unresectable, locally advanced, stage III non-small-cell lung cancer (NSCLC) with a poor prognosis, palliative concurrent chemoradiotherapy (CRT) provided a significantly better outcome than chemotherapy alone, except among performance status (PS) 2 patients. In the present subgroup analysis, we evaluated the effect on patients aged ≥ 70 years (42% of all included) compared with patients aged < 70 years enrolled in the trial. PATIENTS AND METHODS: All patients received 4 courses of intravenous carboplatin and oral vinorelbine. The experimental arm also received radiotherapy (42 Gy in 15 fractions). The included patients were required to have large tumors (> 8 cm), weight loss (> 10% within the previous 6 months) and/or PS 2. RESULTS: The overall survival was increased among the CRT patients in both age groups, but the difference was significant only in patients aged < 70 years (median survival, 14.8 vs. 9.7 months; P = .001; age ≥ 70 years, median survival, 10.2 vs. 9.1 months; P = .09). Patients aged ≥ 70 years experienced better preserved health-related quality of life (QOL) and significantly less hematologic toxicity. The 2- and 3-year survival was significantly increased in both age groups receiving CRT. CONCLUSION: Elderly patients aged ≥ 70 years with unresectable, stage III, locally advanced, NSLCL and a poor prognosis can tolerate CRT with the doses adjusted to age and palliative intent. These results indicate that CRT can provide both survival and QOL benefits in elderly patients, except for those with PS 2 or worse. The male predominance in the ≥ 70-year-age group and the reduced chemotherapy intensity for the patients aged > 75 years might explain the lack of significant survival improvement among those patients aged ≥ 70 years.

Poor prognosis patients with inoperable locally advanced NSCLC and large tumors benefit from palliative chemoradiotherapy: a subset analysis from a randomized clinical phase III trial.

INTRODUCTION: Poor prognosis patients with bulky stage III locally advanced non-small-cell lung cancer may not be offered concurrent chemoradiotherapy (CRT). Following a phase III trial concerning the effect of palliative CRT in inoperable poor prognosis patients, this analysis was performed to explore how tumor size influenced survival and health-related quality of life (HRQOL). METHODS: A total of 188 poor prognosis patients recruited in a randomized clinical trial received four courses intravenous carboplatin day 1 and oral vinorelbine day 1 and 8, at 3-week intervals. The experimental arm (N = 94) received radiotherapy with fractionation 42 Gy/15, starting at the second chemotherapy course. This subset study compares outcomes in patients with tumors larger than 7 cm (N = 108) versus tumors 7 cm or smaller (N = 76). RESULTS: Among those with tumors larger than 7 cm, the median overall survival in the chemotherapy versus CRT arm was 9.7 and 13.4 months, respectively (p = 0.001). The 1-year survival was 33% and 56%, respectively (p = 0.01). Except for a temporary decline during treatment, HRQOL was maintained in the CRT arm, regardless of tumor size. Among those who did not receive CRT, patients with tumors larger than 7 cm experienced a gradual decline in the HRQOL. The CRT group had significantly more esophagitis and hospitalizations because of side effects regardless of tumor size. CONCLUSION: In patients with poor prognosis and inoperable locally advanced non-small-cell lung cancer, large tumor size should not be considered a negative predictive factor. Except for performance status 2, patients with tumors larger than 7 cm apparently benefit from CRT.

Bridging the distance: a prospective tele-oncology study in Northern Norway.

PURPOSE: The University Hospital of North Norway (UNN) is a tertiary-level hospital and has the main responsibility of providing specialized cancer health care in the remote area of Northern Norway. Weekly videoconferences (VCs) have been established to enable clinicians at a local hospital and primary cancer health care providers in five different communities to discuss cases with specialist cancer care services at UNN. In this study, we aimed to evaluate the feasibility of these VCs. METHODS: This is a prospective registration study. Descriptive data were collected at UNN, and for each patient discussed at the VC, a survey was completed by the local health care provider responsible for the patient. RESULTS: During an 18-month period, 167 cases were discussed (101 patients). A median of 7 health care providers participated in each VC. According to the local physicians and nurses, the VCs contributed in 96% of cases to give "quite a bit" or "very much" confidence in adequate patient care. They reported that patient care in 85% of cases would be improved "quite a bit" or "very much" due to the VC. The mean number of days waiting for VC were 2.0 days (range, 0-7; SD, 2.0) and was significantly shorter (P < 0.001) than the estimated time waiting if alternative consultations were to be used (mean, 10.2 days (range, 0-30; SD, 5.8)). CONCLUSION: VC may be a useful supplemental tool to support primary health care providers at local hospitals and remote communities in their effort to offer efficient and high-quality cancer care.

Chemotherapy and quality of life in NSCLC PS 2 patients.

INTRODUCTION: Nearly 40% of patients with advanced NSCLC are in performance status (PS) 2. These patients have a shorter life expectancy than PS 0/1 patients and they are underrepresented in clinical trials. Data on how platinum-based combination chemotherapy affects Health Related Quality of Life (HRQOL) of patients with PS 2 are scarce and the treatment of this important group of patients is controversial. METHODS: A national multicenter phase III study on platinum based chemotherapy to 432 advanced NSCLC patients included 123 patients with PS 2. To explore the treatment impact on HRQOL, the development of HRQOL during the first nine weeks were compared between PS 2 and PS 0/1 patients. We used the EORTC QLQ-C30 and QLQ-LC13 questionnaires. Standardized area under the curve for all HRQOL items, and HRQOL responses classified as better, stable or worse, were compared between the groups. RESULTS: Whereas the demographic data at baseline were well balanced between the groups, the PS 2 patients had significantly worse function and more severe symptoms than the PS 0/1 patients. In response to combination chemotherapy, the PS 2 patients had a more profound improvement of global QOL, cognitive function, fatigue, dyspnea, sleeping problems and appetite loss in comparison to the PS 0/1 group. CONCLUSIONS: PS 2 NSCLC patients seem to achieve valuable HRQOL benefits from platinum-based combination therapy. Prospective clinical studies with predefined HRQOL outcomes in PS 2 patients are needed to confirm these findings.

Treatment outcome in performance status 2 advanced NSCLC patients administered platinum-based combination chemotherapy.

BACKGROUND: There is no consensus regarding chemotherapy to patients with advanced NSCLC (ANSCLC) and performance status (PS) 2. Using data from a national multicenter study comparing two third-generation carboplatin-based regimens in ANSCLC patients, we evaluated the outcome of PS 2 patients. PATIENTS AND METHODS: The 123 PS 2 patients were compared to 309 PS 0/1 patients regarding survival, quality of life (QOL) and treatment toxicity. RESULTS: PS 2 patients had lower haemoglobin, lower global QOL and more pain, nausea/vomiting and dyspnea at inclusion. 68% of PS 2 patients received three chemotherapy courses vs. 85% in the PS 0/1 group (P<0.01). Median and 1-year survival were lower in the PS 2 group, 4.5 vs. 8.9 months and 10% vs. 37% (P<.01). More PS 2 patients needed blood transfusions (P=0.03) and hospitalization (P<0.01). In contrast, PS 2 patients had better relief of pain and dyspnea, and tended to a better global QOL and did not experience more leucopoenia, infections or bleeding. CONCLUSIONS: Despite shorter survival, treatment toxicity was acceptable and PS 2 patients achieved better improvement of pain and dyspnea and tended to better global QOL when compared to PS 0/1 patients.

[Low-grade non-Hodgkin lymphoma in Northern Norway]. / Låggradig non-Hodgkins lymfom i Nord-Noreg.

BACKGROUND: We present a study of treatment outcome and evaluate pre-treatment prognostic factors in patients treated for low-grade non-Hodgkin's lymphoma (LG-NHL) at our institution during a ten-year period. MATERIAL AND METHODS: 169 consecutively registered patients from 1986 to 1996 were retrospectively analysed with regard to demographic, treatment, and disease-specific characteristics. Median follow-up time was 52 months. All patients were diagnosed histologically according to the previous Kiel classification system. Median age was 60 years; the male:female ratio was 1.05:1. RESULTS: The response rate was 66%; median overall survival 8.3 years. Five and ten-year overall survival were 72% and 47% respectively. For stage 1, 2, 3 and 4, ten-year overall survival were 86%, 65%, 33% and 29%. Of the pre-treatment parameters, advanced stage, B-symptoms, poor performance status, bone marrow infiltration, tumour > or = 6 cm, low serum albumin, anaemia, and LD > or = 540 U/l were all related to survival. According to the multivariate analysis, stage, performance status, tumour size, and anaemia were found to be independent prognostic factors for overall survival. INTERPRETATION: The strategy of radiation therapy has proved successful for most patients with stage 1 disease. Independent prognostic factors for overall survival such as stage, performance status, tumour size, and anaemia may be useful guides in deciding when and how to treat.
