Key clinical point: Meta-analysis confirms the detrimental effect of KRAS and BRAF mutations on disease-free survival (DFS) and overall survival (OS) in patients with stage II/III colon cancer, with the effect being enhanced by adjustment for microsatellite instability (MSI).

Major finding: KRAS mutations significantly deteriorated both DFS (pooled hazard ratio [pHR], 1.36; P less than .001) and OS (pHR, 1.27; P = .03), whereas BRAF mutations significantly deteriorated only OS (pHR, 1.49; P < .001), but not DFS. Adjustment for MSI enhanced the effect of KRAS (pHR_DFS, 1.43; P = .001; pHR_OS, 1.33; P = .03) and BRAF (pHR_DFS, 1.59; P = .001; pHR_OS, 1.67; P less than .001) mutations.

Study details: This was a meta-analysis of 9 phase 3 adjuvant trials including 10,893 patients with stage II/III colon cancer.

Disclosures: No specific funding was declared. Some of the authors including the lead author declared receiving research funding and personal fees from and/or consulting or advisory role for various sources.

Key clinical point: Addition of panitumumab (Pmab) to fluorouracil/folinic acid (FU/FA) maintenance therapy significantly prolonged progression-free survival (PFS) compared with FU/FA alone in patients with RAS wild-type metastatic colorectal cancer (mCRC).

Major finding: The trial achieved its primary endpoint with a significant improvement in PFS with the addition of Pmab to FU/FA vs. only FU/FA maintenance therapy (8.8 months vs. 5.7 months; hazard ratio [HR], 0.72; P = .014). The most frequent grade 3 or more adverse event during maintenance in the Pmab arm was acneiform rash (7.2%).

Study details: PANAMA, a phase 2 trial included 377 patients with RAS wild-type mCRC who received induction therapy with 6 cycles of FOLFOX+Pmab. Patients with stable disease, partial or complete remission after induction, were randomly assigned to FU/FA+Pmab (n=125) or only FU/FA (n=123) maintenance therapy.

A fungal infection typically seen in the lungs may have a variety of unusual clinical presentations elsewhere in the body, even raising suspicion of cancer in some cases, a medical resident reported at the annual meeting of the American College of Chest Physicians.

In one recent and unusual presentation, a 58-year-old woman with persistent headaches had skull lesions on computed tomography (CT) was eventually diagnosed with disseminated coccidioidomycosis (Valley fever), a fungal infection endemic to the Southwestern U.S.

The imaging pattern of her head CT was initially concerning for cancer metastasis, according to Sharjeel Israr, MD, a third-year internal medicine resident at Creighton University in Phoenix, Ariz.

However, the subsequent chest CT revealed a suspicious chest mass. A biopsy of that mass led to the correct diagnosis of disseminated coccidioidomycosis, according to Dr. Israr, who presented the case report in an e-poster at the CHEST meeting, which was held virtually this year.
 

Mistaken identity

Coccidioidomycosis, caused by the fungus Coccidioides, usually affects the lungs, according to the Centers for Disease Control and Prevention. However, in severe cases it can spread to other parts of the body. In those cases, it’s referred to as disseminated coccidioidomycosis.

Arizona accounted for about 10,000 out of 18,000 reported Valley fever cases in 2019, according to the latest statistics from the CDC.

Coccidioidomycosis is frequently mistaken not only for cancer, but also for rheumatic conditions and bacterial infections, according to Valley fever specialist John Galgiani, MD, director of the Valley Fever Center for Excellence at the University of Arizona in Tucson.

“Where Valley fever is common, it should very frequently be in the differential for masses that are thought to be cancer,” Dr. Galgiani said in an interview. “This case is a good example of that.”
 

Challenging case

In an interview, Dr. Israr said the case was challenging to crack despite the fact that Valley fever is very common in Phoenix.

“It was definitely on the differential from the get-go, but it was very, very low our differential, just based on the presentation that she had,” said Dr. Israr.

The patient had history of diabetes and presented with headaches for 4 weeks. However, she had no pulmonary symptoms or meningeal signs, according to Dr. Israr.

A head CT revealed multiple osseous skull lesions and a left temporal lobe lesion.

“The fact that this patient had lesions in the skull, specifically, is something that raised our initial red flags for cancer – especially since she presented with just a headache as her only complaint,” he said.

The imaging pattern was concerning for metastasis, according to Dr. Israr, particularly since a subsequent CT of the chest showed multiple pulmonary nodules plus a 7.7-cm mass in the right lower lobe.

Once the biopsy confirmed coccidioidomycosis, the patient was started on fluconazole 600 mg twice daily, according to Dr. Israr.

Although severe disseminated coccidioidomycosis can be difficult to treat, the lung lesion had decreased in size from 7.7 cm to 4.2 cm about 3 months later, Dr. Israr said.

“At the end of the day, she didn’t have cancer, and it’s something that we’re treating and she’s actually doing better right now,” Dr. Israr said in the interview.

Dr. Israr and coauthors of the case reported they had no relevant relationships to disclose.

Key clinical point: Delaying surgery after completing neoadjuvant chemoradiotherapy (CRT) could be a risk factor for worse outcomes in patients with locally advanced rectal cancer with poor or no pathological response to preoperative CRT.

Major finding: A longer vs. shorter waiting period between surgery and end of CRT was associated with worse overall survival (5 years: 67.6% vs 80.3%; 10 years: 40.1% vs 57.8%; P < .001) and disease-free survival (5 years: 59.6% vs 72.0%; 10 years: 36.2% vs 53.9%; P < .001).

Study details: Findings are from a retrospective analysis of 1,064 patients who underwent CRT and surgery for locally advanced rectal cancer and showed partial or no pathological response to neoadjuvant CRT. Wait time between CRT completion and colorectal surgery categorized patients into shorter (8 weeks or less; n=579) or longer (greater than 8 weeks; n=485) interval groups.

Disclosures: The study did not declare any source of funding. No conflict of interests was reported.

Key clinical point: Primary tumor resection (PTR) of asymptomatic tumor followed by systemic therapy is associated with a significantly higher 60-day mortality than systemic therapy alone in patients with nonresectable metastatic colorectal cancer (mCRC).

Major finding: Deaths within 60 days of randomization were significantly higher in the PTR vs systemic therapy alone (11% vs 3%; P = .03) arm with elevated levels of lactate dehydrogenase (P = .046), neutrophils (P = .04), aspartate aminotransferase (P < .001), and alanine aminotransferase (P = .002) being associated with higher 60-day mortality in the PTR arm.

Study details: CAIRO4 is a randomized phase 3 trial including 198 patients with nonresectable mCRC and asymptomatic primary tumor randomly assigned to systemic therapy alone or PTR followed by systemic therapy with palliative intent.

Disclosures: The study was funded by Dutch Cancer Society and Hoffmann-La Roche. Dr. DEW van der Kruijssen, Dr. GR Vink, Dr. JHW de Wilt, and Dr. M Koopman reported receiving grants and/or nonfinancial support from various sources including Hoffmann-La Roche Ltd.

A biopsy of the lesion was performed which showed an increased number of eccrine glands and blood vessels within the dermis. Some areas showed an increase in adipocytes and smooth muscle bundles. The changes were consistent with eccrine angiomatous hamartoma (EAH).

The boy was referred to vascular laser therapy for treatment of the lesion.

EAH is a rare benign vascular growth characterized by an increased number of mature eccrine glands and blood vessels in the dermis and subcutis. The lesions are mostly present on the extremities, but cases of diffuse congenital lesions and lesions on the face and trunk have also been described. The lesions can be seen at birth or during the first years of life in about half of the cases, and the others tend to occur later in puberty and rarely in adulthood^.1

Clinically, EAH lesions present as red, yellow to brown papules and plaques. Different dermoscopic patterns have been described which include the popcorn pattern that presents as yellow, confluent nodules with popcornlike shapes over a background of erythema, and linear arborizing vessels. The spitzoid pattern are brown globules on a background of erythema and pseudoreticular pigmentation around the globules. The verrucous hemangiomalike pattern has a bluish-white hue, reddish-blue or bluish lacunae, as seen in our patient.^2-4

Most of the lesions are asymptomatic, but in some patients, they can be associated with pain, hyperhidrosis, and sometimes bleeding. Hyperhidrosis has been reported early in the presentation or during puberty or pregnancy. Our patient had started on amphetamines when hyperhidrosis occurred. Hyperhidrosis is a knowns side effect of this type of medication and may have had a role in the increased sweating noted on the hamartoma.

EAH can clinically look like verrucous hemangiomas, angiokeratomas, and vascular malformations, and histopathology may be needed to differentiate between them. Eccrine nevi and EAH can be similar. Hyperhidrosis is an early and predominant component of eccrine nevi, compared with one-third of EAH.

The exact etiology of this lesion is not known. It is thought to be caused by an abnormal differentiation of the epithelium, adnexal structure, and the mesenchyme during organogenesis.³ No other associated conditions have been described with EAH.

EAH are benign lesions that rarely require treatment. If the lesions are symptomatic or because of cosmetic reasons, they can be removed surgically. There are some reports of successful treatment with pulse dual-wavelength sequential 595- and 1064-nm lasers.⁵ Botulinum toxin has also been used in cases of symptomatic hyperhidrosis.

The verrucous hemangiomalike pattern has a bluish-white hue, reddish-blue or bluish lacunae, as seen in our patient.^2-4

Most of the lesions are asymptomatic, but in some patients, they can be associated with pain, hyperhidrosis, and sometimes bleeding. Hyperhidrosis has been reported early in the presentation or during puberty or pregnancy. Our patient had started on amphetamines when hyperhidrosis occurred. Hyperhidrosis is a knowns side effect of this type of medication and may have had a role in the increased sweating noted on the hamartoma.

EAH can clinically look like verrucous hemangiomas, angiokeratomas, and vascular malformations, and histopathology may be needed to differentiate between them. Eccrine nevi and EAH can be similar. Hyperhidrosis is an early and predominant component of eccrine nevi, compared with one-third of EAH.

The exact etiology of this lesion is not known. It is thought to be caused by an abnormal differentiation of the epithelium, adnexal structure, and the mesenchyme during organogenesis.³ No other associated conditions have been described with EAH.

EAH are benign lesions that rarely require treatment. If the lesions are symptomatic or because of cosmetic reasons, they can be removed surgically. There are some reports of successful treatment with pulse dual-wavelength sequential 595- and 1064-nm lasers.⁵ Botulinum toxin has also been used in cases of symptomatic hyperhidrosis.

A biopsy of the lesion was performed which showed an increased number of eccrine glands and blood vessels within the dermis. Some areas showed an increase in adipocytes and smooth muscle bundles. The changes were consistent with eccrine angiomatous hamartoma (EAH).

The boy was referred to vascular laser therapy for treatment of the lesion.

EAH is a rare benign vascular growth characterized by an increased number of mature eccrine glands and blood vessels in the dermis and subcutis. The lesions are mostly present on the extremities, but cases of diffuse congenital lesions and lesions on the face and trunk have also been described. The lesions can be seen at birth or during the first years of life in about half of the cases, and the others tend to occur later in puberty and rarely in adulthood^.1

Clinically, EAH lesions present as red, yellow to brown papules and plaques. Different dermoscopic patterns have been described which include the popcorn pattern that presents as yellow, confluent nodules with popcornlike shapes over a background of erythema, and linear arborizing vessels.

Key clinical point: Continuous positive airway pressure (CPAP) therapy in patients with severe COVID-19 who are not likely to benefit from invasive mechanical ventilation (IMV) does not confer a survival advantage over oxygen alone.

Major finding: The overall 30-day mortality rate was 75.6% in the oxygen group vs 77.7% in the CPAP group (Pearson’s Chi-square, P = .8).

Study details: The data come from a retrospective multicentre cohort study involving 479 patients with COVID-19 ineligible for IMV from 7 UK hospitals. Patients given CPAP were compared with those receiving oxygen therapy.

Key clinical point: Smokers have a significantly higher risk for COVID-19 related hospital admission and mortality than nonsmokers.

Major finding: Current smokers had an 80% higher risk for hospitalization than never-smokers (odds ratio, 1.80; 95% confidence interval, 1.26-2.29). Smokers who smoked more than 20 cigarettes a day had a 6.11-fold higher risk of dying from COVID-19 than never-smokers.

Study details: The data come from an observational study of 421,469 individuals from the UK Biobank.

Disclosures: The study was supported by individual grants to several authors. PS Tan, CAC Coupland, MR Munafò, J Hippisley-Cox, and A von Ende reported relationships with pharmaceutical companies and/or research organizations. The remaining authors declared no conflict of interests.
