Cost-Effectiveness of Adjuvant Chemotherapy in the Treatment of Early-Stage Colon Cancer

The Cost-Effectiveness of Requesting a Complete Blood Count (CBC) in the Management of COVID-19 in Saudi Arabia

Background: Since the beginning of the COVID-19 pandemic, studies have attempted to determine the value of the different laboratory investigations. This study aims to assess the cost-effectiveness of requesting a complete blood count (CBC) for COVID-19 patients, as opposed to ordering a COVID-19 antibody titer in Saudi Arabia. Methods: The prices of a CBC, COVID-19 PCR, and antibody titer were obtained from 40 healthcare establishments in Saudi Arabia, between January and February 2022. Results: Requesting a CBC is significantly cheaper than requesting a COVID-19 antibody titer, which was available in almost all of the establishments, as compared to COVID-19 PCR and antibody titer testing. The investigation prices did not differ significantly between hospitals and private laboratories, nor across cities in Saudi Arabia. Conclusions: CBC, which provides valuable information on the patient’s condition and prognosis, is a cost-effective and widely available tool for managing COVID-19. The price and availability of CBC warrant it to be included in the COVID-19 management protocols.

Suboptimal Completion Rates, Adverse Events, Costs, Resource Utilization, and Cost Impact of Noncompletion in Oral Adjuvant Capecitabine-Based Chemotherapy in Patients With Early-Stage Colon Cancer

BACKGROUND

Suboptimal completion of chemotherapy, which may involve reduced patient adherence, remains a serious issue and leads to reduced treatment efficacy. This study assessed the completion rates, risk factors for noncompletion, and cost impact for noncompletion in patients on capecitabine monotherapy (Cape) or capecitabine with oxaliplatin (CAPOX) for the adjuvant treatment of early-stage colon cancer.

METHODS

Patients with a diagnosis of early-stage colon cancer between April 2013 and March 2017 were retrospectively identified. Treatment completion was evaluated. Multivariate logistic regressions analyses were used to assess the baseline factors associated with noncompletion. Adverse events, costs, healthcare resource utilization, and cost impact for noncompletion were investigated.

RESULTS

A total of 673 patients met the eligibility criteria, of which 382 (57%) were treated with Cape and 291 (43%) with CAPOX. The overall completion rate for adjuvant therapy was 40% (Cape 46%; CAPOX 33%). Noncompletion was associated with CAPOX treatment and higher healthcare costs within 6 months prior to chemotherapy. The 6-month unadjusted total healthcare costs were $44,444 for Cape and $71,247 for CAPOX. The nonchemotherapy costs were 41% higher for noncompleters than completers in both treatment groups (P = .002).

CONCLUSIONS

The real-world completion rates for adjuvant capecitabine-based chemotherapy in early-stage colon cancer patients are low. Noncompletion of therapy is associated with higher baseline healthcare costs. The nonchemotherapy costs are significantly higher in noncompleters than completers, highlighting the financial burden of managing adverse events and preexisting comorbidities, which may lead to early discontinuation of therapy. Effective strategies to optimize completion of oral chemotherapy may consider adherence monitoring.

Contribution Of Care Source To Cancer Treatment Cost Variation In The US Military Health System

The US Military Health System (MHS) provides universal access to health care for more than nine million eligible beneficiaries through direct care in military treatment facilities or purchased care in civilian facilities. Using information from linked cancer registry and administrative databases, we examined how care source contributed to cancer treatment cost variation in the MHS for patients ages 18-64 who were diagnosed with colon, female breast, or prostate cancer in the period 2003-14. After accounting for patient, tumor, and treatment characteristics, we found the independent contribution of care source to total variation in cost to be 8 percent, 12 percent, and 2 percent for colon, breast, and prostate cancer treatment, respectively. About 20-50 percent of the total cost variance remained unexplained and may be related to organizational and administrative factors.

Marked Prognostic Impact of Minimal Lymphatic Tumor Spread in Prostate Cancer

BACKGROUND

Nodal metastasis (N1) is a strong prognostic parameter in prostate cancer; however, lymph node evaluation is always incomplete.

OBJECTIVE

To study the prognostic value of lymphatic invasion (L1) and whether it might complement or even replace lymph node analysis in clinical practice.

DESIGN, SETTING, AND PARTICIPANTS

Retrospective analysis of pathological and clinical data from 14 528 consecutive patients.

INTERVENTION

Radical prostatectomy.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The impact of L1 and N1 on patient prognosis was measured with time to biochemical recurrence as the primary endpoint.

RESULTS AND LIMITATIONS

Nodal metastases were found in 1602 (12%) of 13 070 patients with lymph node dissection. L1 was seen in 2027 of 14 528 patients (14%) for whom lymphatic vessels had been visualized by immunohistochemistry. N1 and L1 continuously increased with unfavorable Gleason grade, advanced pT stage, and preoperative prostate-specific antigen (PSA) values (p<0.0001 each). N1 was found in 4.3% of 12 501 L0 and in 41% of 2027 L1 carcinomas (p<0.0001). L1 was seen in 11% of 9868 N0 and in 61% of 1360 N1 carcinomas (p<0.0001). Both N1 and L1 were linked to PSA recurrence (p<0.0001 each). This was also true for 17 patients with isolated tumor cells (ie, <200 unequivocal cancer cells without invasive growth) and 193 metastases ≤1mm. Combined analysis of N and L status showed that L1 had no prognostic effect in N1 patients but L1 was strikingly linked to PSA recurrence in N0 patients. N0L1 patients showed a similar outcome as N1 patients.

CONCLUSIONS

Analysis of lymphatic invasion provides comparable prognostic information than lymph node analysis. Even minimal involvement of the lymphatic system has pivotal prognostic impact in prostate cancer. Thus, a thorough search for lymphatic involvement helps to identify more patients with an increased risk for disease recurrence.

PATIENT SUMMARY

Already minimal amounts of tumor cells inside the lymph nodes or intraprostatic lymphatic vessels have a severe impact on patient prognosis.
